>But it only takes one copy of a movie getting onto thepiratebay to make it accessible to everyone who wants it.

Unlocking the DRM on that one movie allows you to pirate that one movie, not all movies. Finding a security bug for one OS allows you to exploit that particular OS.

>So if DRM cannot prevent every attempt at circumvention, it's useless and can only serve to hinder legitimate use of the product.

No, if something even serves as a mild hurdle, it is still beneficial.

Given the abundance of hundreds, and in some cases thousands of vulnerabilities, it seems securing any OS is an impossible task. To take smartphones phones as an example, a vast vast majority of phones have had vulnerabilities which let you root/jailbreak them.

>No, I don't. The fact that some people accept the deal doesn't prove that there's nothing wrong with it. In this case, the seller unilaterally went back on the deal without the customers being involved at all.

You do, because I don't accept the argument you made. Your broad claim that DRM == disrespecting consumers doesn't seem to be borne out by the market. So it seems we've reached a bit of an impasse.

>The purpose of DRM is to prevent piracy. This has mostly been a failure.

You have to actually demonstrate that it is a failure. Whats plain to see for anyone is that products like adobe photoshop for e.g. are going from 'little league' DRM to 'major league' DRM + subscription and are making even more money. Its fine to lament at how the world sucks, but its important to be realistic and fact based when doing so.
