Here we are again, and this thread is full of comments about whether this was afoul of DMCA or whether there's a way to adjust the system so that these claims will be more costly to the claimant.
We need to break open the head here, people! We're scientists, right? Step back from your political ideologies and your fears and tell me what the real problem is with this biological system.
Right: it's that a single actor can make the decision to censor these things. It's fundamentally a weak link problem.
Whether or not we fix DMCA, which I'm sure we will, we need to fix the problem that the weak link exists in the first place. A centralized Youtube will not do for the information age. Our organism must build immunity such that, no matter the tantrums of the state, nobody is capable of giving in and handing over the lollipop.
