First link is kind of one of those paranoia scenarios though. There's a bit of sceince involved that if you want to go to that extreme then you as a sysadmin has more concerns to deal with.
As for the NSA one, meh. The RSA algorithm has been implemented by other sources given PKI and the Diffie-Hellman algorithm is public domain essentially. So just because RSA was bought out doesn't mean the RSA algorithm itself is unsafe, you just have to know where the algorithm came from.
