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

These measures are simple enough to bypass just by disabling JavaScript in my browser. 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.

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.
