I still think the NSA employs Linux devs so they can deliberately insert flaws. Why would they not? It would be very easy. But every time I mention it people reply "But but many eyes! They'd get caught!"
I want to point out that they could similarly hire someone working at microsoft, or get someone up for a position there, to do this and it would be at least as hard to detect...
To contribute to the Windows kernel you'd have to get someone hired by Microsoft, who presumably check their employment history (maybe), they have to actually go and work for Microsoft, etc. Obviously none of that is impossible but it's also obviously much harder than sending a patch to a mailing list.
