JavaScript User Prohibitions Are Like Content DRM, But Even Less Effective (teleread.com) 188

Robotech_Master writes: It always puzzles me whenever I run across a post somewhere that uses JavaScript to try to prevent me from copying and pasting text, or even viewing the source.

It seems like these measures are very similar to the DRM publishers insist on slapping onto e-books and movie discs—easy to defeat, but they just keep throwing them on anyway because they might inconvenience a few people.

    Nobody expects a "No Trespassing" sign to stop anybody from really doing anything they shouldn't, heck, you shouldn't expect your home locks to stop a burglar, and no, nobody thinks a "No Guns allowed" sign stops anybody with firearms.

    But once you say "Stop, don't do it" then anybody making the effort to continue, no matter how trivial, has made an intentional action on their part.

      You might have been right if the DRM applied aligns 100% with legal boundaries. That is, allow what's legal and prevent illegal uses. And keeps doing so as circumstances / place / time changes.

      But in practice, it never does. DRM on an e-book that prevents copying period, also prevents copying small snippets to use as quote. Which is perfectly legal - see "fair use".

      Unlike author claims, the DRM on Blu-rays is far from broken. If it were, playing them on open source operating systems like Linux would be as easy as playing DVD's on there. But that's not the case. There's databases of per-disk decoding keys floating around. There's libraries that emulate some sort of virtual machine that's built into 'authorised' playback devices. There's other libraries that cut through parts of the DRM bullshit, or attempt to streamline the process.
      But all of these are kludges, there's no 100% guarantee that a random Blu-ray will play (using open source, at the moment), and it's a lot of hassle for users who are just trying to play discs they legally purchased. I'm sure it's only a matter of time before the DRM on Blu-rays will be as irrelevant as that on DVD's, but we're not there yet and in any case it doesn't change the annoyance factor one bit.
      What's more: these issues mostly bother legal users, those who download movies illegally couldn't care less. But the DRM will still be in place as long as the discs itself. Regardless of legalities.

      There's countless examples like that. The technical measures are practically never capable of following legal developments, nor do they adapt to local jurisdiction. Or have a built-in kill switch that 'frees' a product when legal restrictions end. In my personal opinion: DRM simply lowers the value of products that it's applied to, PERIOD. Sometimes to the point of making those products worthless. Some DRM is just more annoying or difficult to circumvent than others.

      • In my personal opinion: DRM simply lowers the value of products that it's applied to, PERIOD. Sometimes to the point of making those products worthless.

        This is the reason I don't buy Blu Ray disks, ever, but continue to buy DVD's. The first thing I do with DVD's I buy is to extract them to my home media server, to keep the original disk safe and to be able to watch the movie from any computer in my house. Blu Ray makes this so painful that I just won't buy any. That type of access restriction lowers the value of Blu Ray to zero.

        I totally get why illegal movie downloaders claim that the movie studios are the biggest cause of illegal movie downloading.

        I'm sorry to hear that your fingers are broken and you can't type up your paper / article / whatever. By the way, how did you manage to write the rest of the words, including the proper citations of the text you wanted to copy? And hoooo boy, what if you wanted something from a physical book? Scan and OCR or just get lazy and take a photo of the page?

      • DRM doesn't plug the analog hole. If you wan't to copy small snippets from a book, type them in by hand like I do. The trivial cut-and-paste blocks aren't intended to prevent copying, only to make it more inconvenient. Agreed, it would be nice to have technological countermeasures better aligned with the legal restrictions, but the technology changes a lot faster than the legal framework for dealing with technology, and lawyers don't make any effort to align the law with the technology, do they?

        A sign is a notification...
        A notification on a website could be placed within the text of the site itself, using javascript is a very poor attempt to do more than just post a sign...
        It's more akin to an extremely low fence.

        The worst part is that whoever requests stuff like this be added generally believe it's actually effective, but all it does is serve to irritate users.

      Except that keeping people out isn't the point of "No Trespassing" signs. A legal requirement of trespassing is that you have to be told that you are not allowed there. Thus if there are no signs then you cannot be prosecuted unless an authorized agent finds you in the act and requests your departure.

    I am a photographer, and I have no problem sharing this:

    If you want to get around the image obfuscation used by most photo sharing sites and more and more news sites, open up firefox, and go to view -> page style -> no style. That usually gives you the actual image displayed somewhere in the resulting page. No plugins needed.

    If you want to better ensure your name stays with an image, watermark it, and add meta-data. Depending on how annoying the watermark is, someone could take the time to paint it out, and meta data is trivial to strip. As the saying goes, if you can see it, you can take it.

      I like Flickr's attempt at blocking the image. If I want to download an image in Chrome I normally right click the image and hit S on the keyboard. Then save it somewhere. If a Flickr image is marked as download disabled and I right click an image in Chrome and click S I still get given a familiar save as dialogue. Except this time since Chrome doesn't think I clicked on an image it downloads the page. .... with the image at every available resolution. Just sorting the resulting folder by size gives the image.

    Years ago, fark.com went from external images to hosted images. I didn't see the endgame.

    This week, JavaScript is required to load the images. It's vendor lock in all over again. Because who uses an external host if you can just click upload?

      As a matter of fact, if you've Javascript disabled, there's no "upload" to click and you have to use an external host (Fark then downloads the image from there onto their servers).

The page then presents just fine without having run the javascript to display the advertisement.

      Basically, you can google anything with "javascript disable" and get developers asking how to fuck their users in the pee hole. Often, there's an answer.

      Also note: the real workaround for this isn't globally disabling javascript, though if everyone did that the web would shape up immediately. The real workaround is the various -monkeys that let you redefine pieces of javascript locally. Many sites go through several hoops to prevent loading on a browser that won't run their shitscript, but redefining parts and/or loading your own CSS can get you around most of it.

That's a pretty far cry from disabling a hotkey, let alone a program menu item (fwiw, copy paste still technically works on the pages that try to disable it too, they just don't let you select text in the first place by intercepting the mouse click, so there's never anything to copy).

                      Following the stack overflow links I was more wondering about the idiotic approaches many use to accomplish that goal, and I did not really figure by reading them what ctrl-U was supposed to do.

                      One of the big problems with writing a browser that does what the user wants is how aggressively ludicrous the javascript devs can be. For instance, many browsers have a setting that disables the ability of right click to be controlled from the HTML, but of course javascript can POLL this flag, and act on the result. The browser shouldn't be leaking user state like that, and it certainly shouldn't allow a savvy user to be asked to pull down their pants and bend over. It's totally possible to create a bro

    • You can do things like block the default behavior of the hotkeys and stuff. But you basically can't stop someone from getting the source code, because the web is open.

    Another possibility is they are trying to avoid getting sued by content providers- that they have applied best practices to protect media.

    Some of the UI restrictions can be evaded just by pressing a special key like "shift" or "ctrl" while using the mouse and it does not require to disable javascript. I was so frustrated once that I copied the entire text from the page and posted it as a comment to tell them look, I can copy and paste.
    • The probably thought that you just loved their content so much that you were willing to type the whole thing out in order to better remember it. Now they'll disable copying comments so that others won't copy and paste from there! (Only half funny, unfortunately)

    I would venture to say that it inconveniences more than a few, the majority of whom have no idea there is an alternative. Typically Joe Sixpack is clueless a click bait victim and the bread and butter of 90% of content sellers.

  • You got to realize that someone knowledgeable in physical locks can bypass them as easy as you can bypass Javascript right click popups. Yet both still reduce undesirable actions, such as your story being reposted in full on someone's blog without giving credit, link to the source or a chance for you to make money on ads.

    It makes a difference when you at least communicate your wishes clearly. Not saying that copying is illegal, or implementing this behavior is best policy, just that it at least significantl

    Sometimes they don't even notice.

    There was this site with "lessons" in using some API or library. There were code examples. And if you tried to select and copy, to paste an example into a compiler, a dialog would pop up telling you that the content is copyrighted and you're not allowed to copy it.

    And at the bottom of the page was a survey, "What can I do to improve these lessons?"

    I filled it out, with my email and a sarcastic comment about the copy restriction - that maybe forcing people to retype the examples isn't the best way of teaching. The owner of the site wrote me with a solemn apology, informing me that she didn't even notice the (dis)functionality was in place, and that it just got installed with the CMS and she didn't disable it because she didn't know it was there...

    So... whoops?

  • Are sites which say enter your email address twice, but won't let me cut and paste the value from the one field to the other by trapping keyboard events. Yeah I get it, you're trying to stop email typos, but there are other, less annoying ways to deal with this problem - a confirmation email for example - and the chances are the site has one of those too.

    You overestimate the average user.
    They have no idea that that stuff can be bypassed so easily.
    If they did know, they'd think it's too much work.
    Then they'd forget about that being possible.
    • They would see that the person who provided them the content didn't want them to copy and paste and was willing to comply with the request. Sheep! (Half funny)
  • Yes, we all know that if they let you look at the page, your computer will download all the associated files and you'll have them. Just taking the files out of your Firefox cache is an obvious solution. Going in with developer tools already open is another one.

    That being said, most people don't even try these measures anymore. They used to be a lot more common. But even the average web user is getting more sophisticated.

    The new effort is to try to bake DRM into the browsers themselves.

  • ...in the not-too-distant future, the html document you requested will not load, and you'll be shown a short notification instead, saying "please use an OS and browser that comply with our DRM policy"? I am already seeing lots of messages of that flavor while I'm browsing the web using Linux/Firefox, tracking disabled. The claim is that I am trying to view valuable content without paying for it (pop-under windows and user tracking being the currency).
