How exactly is the fact that someone can take down an arbitrary non-infringing file without any consequences to them not an indictment against the DMCA?
I was about to ask the same question... There is a right way and a wrong way to handle potentially infringing material on the internet, and unfortunately, the DMCA has repeatedly shown time and time again that it is definitely the 'wrong' way. This situation is just another example of how the legislation fails at protecting the consumer, fails at really protecting a company's intellectual property, and furthermore, can potentially threaten the livelihood of people writing code or providing media on the web.
It's a relic of an era that was almost two decades ago.
