I've blogged about this in the context of Lancaster's illegal, constant general surveillance of the general population (see 4th amendment, 1st, 14th) through a network of now 165 high-powered, inter-connected video cameras, run by an organization with no accountability whatsoever to the public.
I don't have much more to say except this: organize, force them to stop.
I just found this old post from 2006 referencing the NSA and Microsoft's China censorship.
So, then, Microsoft, I’d expect this is consistent behavior, you’ve done it before, you’re likely to do it on behalf of other countries, and given the Patriot Act and NSA spying on US citizens, you’re doing it within the US on US citizens? I'm baffled and repulsed.
