Microsoft's Vista had help from the NSA

Bruce Schneier:

It's called the "equities issue." Basically, the NSA has two roles: eavesdrop on their stuff, and protect our stuff. When both sides use the same stuff -- Windows Vista, for example -- the agency has to decide whether to exploit vulnerabilities to eavesdrop on their stuff or close the same vulnerabilities to protect our stuff. In its partnership with Microsoft, it could have decided to go either way: to deliberately introduce vulnerabilities that it could exploit, or deliberately harden the OS to protect its own interests.

A few years ago I was ready to believe the NSA recognized we're all safer with more secure general-purpose computers and networks, but in the post-9/11 take-the-gloves-off eavesdrop-on-everybody environment, I simply don't trust the NSA to do the right thing.

Which leads back to this post.
