I agree that it's a shame, but rather than blaming the RIAA, I blame it on the pirates. The widespread acceptance of piracy among users of BitTorrent is what is ruining BitTorrent, not people asserting their voluntarily-granted contractual rights (RIAA).
That my friend is as anti free speech as it gets, and this censorship really erodes
Actually, by flinging about these terms in an incorrect manner, you are damaging the ability of real defenders of free speech to actually defend free speech. You see, MS is just a company; they can make their software work as they want; that is their right to free speech being excercised. If you don't like it, use different software. Only the government (or, indirectly, entities that have achieved governmental capture) can actually infringe on free speech.
