Pointing out their weaknesses actually helps Microsoft. Pointing out their piss-poor public relations should also help them, but they seem to be so arrogant that they ignore it. Believe it or not, not everyone is a thief, they just want to challenge silly claims that a product is secure.
As for your DRM comments, I said before that Microsoft is responsible for not making their Vista limitations clear.
They are not limitations of Vista. They are limitations of DRM. I now believe with the vast majority of uninformed people blaming Microsoft for the restrictions of DRM that Microsoft simply should've never supported playback of such content. Complying with AACS standards might turn out to be a nightmare.
