Surprise!

by Tim Lee on September 12, 2006 · Comments

Randy Picker has a great dissection of the Unbox licensing agreement. He finds three notable (mis)features: first, the software reserves to right to phone home to look for software updates and enforce the terms of the DRM software. Second, if you uninstall the software, Amazon reserves the right to delete all of your purchased movies and terminate your right to watch them. And finally, Amazon reserves the right to change your rights under the EULA unilaterally.

As Prof. Picker notes, these terms are not likely to be a big hit with consumers:

I suspect my tone sounds a tad hostile but I don’t really mean it that way. For better or worse, this is exactly the design we should anticipate with digital rights management software and therein lies the central market conundrum for DRM. Indeed, I am surprised that folks are surprised by the design. It may be sensible for the law to validate DRM as it does in the Digital Millennium Copyright Act, as I have argued before, but that is a far cry from saying the consumers will embrace it. The law should facilitate sales of purple shirts with pink and yellow polka dots, but no one should buy them.

Given that Amazon intends to support both online sales and rentals, it either needs to implement built-in expiration or some sort of phoning home to the mothership. The rental structure contemplates a 24-hour window in which to watch the download and a 30 day period in which to start watching.

I’m surprised that he’s surprised that people are surprised. (Sorry, I couldn’t help myself) I’ll explain why below the fold.


In mainstream policy debates over DRM, the pro-DRM side leans heavily on the analogy between physical locks and digital DRM “locks.” People have strong intuitions about what a lock is, how it works, and why they’re useful, and so it’s easy to tap into those intuitions to make your case for deploying DRM, and for giving DRM special legal protections. “We use physical locks to keep people from stealing physical stuff, right?” they say. “Why shouldn’t we have digital locks to protect digital stuff?”

This debate has been going on, at varying levels of intensity, for close to a decade now. Critics of DRM have failed to come up with an alternative way to frame the debate, so the pro-DRM framing has tended to dominate the discussion. Journalists, lawmakers, academics, and the general public have largely internalized the notion that digital rights management is like a lock for digital stuff.

OK, so now along come products like the Sony BMG CD-DRM and Amazon Unbox. It does creepy stuff like installing itself without permission, resisting removal, and phoning home to the mothership. And people say, “Hey wait a minute, this digital lock isn’t behaving like a physical lock at all! Sure, we agreed that digital locks are a good idea, but we didn’t want them to behave like this.

But the problem isn’t that the digital lock was badly designed. The problem is that the concept of a digital lock is incoherent. In order to build software that approximates the behavior of locks in some respects, you’ve got to make design choices that make it very un-lock-like in other respects. The “physics” of bits is just different than the physics of atoms.

But most people don’t realize that. I suspect Tom Merritt is one of them. Based on his Wikipedia entry at least, I don’t see anything that would indicate he’d have a deep understanding of how DRM works. He probably has the same misleading mental model of DRM that most people do. So when he discovers that DRM software is doing creepy stuff, I think it’s perfectly natural for him to be surprised.

    Actually, I think the "locks" analogy is fine. The problem is who holds the keys.


    If I buy a DVD player in Canada and a DVD in Europe, I (probably) can't play the DVD on the player because of the DRM (region coding) "lock". This is a lock on my property (I bought both the player and the disk), but it's actively preventing me from using my property. Because I don't hold the "keys", I can't remove the lock.



    The lock is applied by other people before they sell me the property, and they keep the keys.



    Now imagine that happening with houses, and you see why I quite like the "locks" analogy. :-)


  • Critics of DRM have failed to come up with an alternative way to frame the debate, so the pro-DRM framing has tended to dominate the discussion.


    Maybe they (the critics of DRM) have not received as much press coverage, but they certainly have come up with very effective counter-arguments.


    In particular, the 'lock' analogy is not a good one. Ed Felten makes the point of how important the picking the right analogy in a podcast interview "Silver Bullet 005 -An interview with Ed Felten" which you can find by Googling without much difficulty.


    Ed makes the point that DRM is really deliberate incompatibility, and how strange it would be if someone wanted to design a special antenna for a TV that was incompatible with all existing broadcast standards, and then wanted that incompatibility to be protected by law. We then would find DRM very strange indeed, right?


    I would actually take it a step further, and suggest that the "contracts" that the monopolies that controll media distribution are trying to force down everyone's throat as part of a content download, should, as a matter of public policy, be made unenforcable. There is ample precedent for this in the many consumer protection laws which exist (for example 'lemon laws') where consumers, no matter what some large corporation may put in a 'contract' have certain well-defined rights.


    The moral basis for such a legal impostion of contractual terms is the inferior bargaining position of each individual consumer, whose rights are protected through government action, government action which is derived from consumers interests, as articulated through democratic and transparent processes.

    Hmmm I admit Im a fan of DRM, but the digital lock analogy is one Im not fond of. You did a good job setting up the strawman but I dont think thats the prominent view. DRM as digital contracts makes more sense, and should prevent folks from (at least a few) unwelcomed surprises when they read the fine print.
  • You are correct that the "critics of DRM have failed to come up with an alternative way to frame the debate". I also don't think that you have gone far enough in exposing the "creepy stuff" this technology can do.




    1. One of the obvious reasons that the downside of DRM has not been adequately exposed is that the mass media has a tendency to simply publish pro DRM press releases as submitted. For example, while the Sony BMG fiasco was in full swing neither the NY Times nor PC Magazine provided any truly informative articles. On the other hand, the Washington Post, I believe, did a good job of exposing the implications of the Sony Rootkit.





    2. The lock analogy is good at the superficial level, if you don't think too much. DRM technologies actually represent a "new" way in "protecting" supposed intellectual property. Basically it gives the content owner the right to break into your property and trespass for the purpose of preventing you from using it. Basically, the content provider can act in any arbitrary and capricious manner they wish while the customer is left defenseless.






    3. The use of DRM technologies is superficially about preventing piracy and makes for good press. The undisclosed intent is to lock the consumer into a company's technology. While this is obvious, I think, there is a hidden agenda, dirty tricks, for example. Companies use dirty tricks all the time, in this case, DRM technologies could be used to disable a competitors product.






    4. Computers are extremely complex. The use of DRM, to a large degree, depends on the use of stealth and non-standard procedures. What this means is that DRM technologies are subject to the law of unintended consequences. Should a problem occur, the majority of users will probably not be able to fix their computer and will also be unaware of what caused the problem. I seriously doubt that a DRM program would actually inform the user that it caused a problem. Needless to say the cost of repairing your computer, reinstalling all the software, and manpower involved will be unfathomable.





    5. In the end, DRM technologies will never work, past history demonstrates that it can always (at least so far) be hacked.
