I am dismayed and disgusted with the NSA as much as the next guy, maybe more than the next guy, but suggesting they had anything to do with stick a root backdoor in the kernel is a stretch. I guess it is possible but seems pretty unlikely. Saying it had anything to do with BK just means you didn't read the original article. BitKeeper found the problem that was in the CVS tree. BitKeeper itself was never compromised.
