Sorry, RSA, I'm just not buying it
I don't think the, "We trusted the NSA" explanation makes them look stupid or negligent.  This article does reference the fact that people are now retroactively claiming understanding of some of these revelations, but I think the writer forgets that this might apply to him as well.NOW it makes perfect sense to see how terrible this is, but we haven't always just blatantly assumed the NSA was out to get us.  They used to not have the worst reputation in the world in the security community, right?  I'm not the best authority for this, but from what I could gather they played a kind of spooky-but-helpful role prior to the Snowden leaks in the intelligence community - that is, you could generally trust they were thought to have the community's best interest at heart, even if they couldn't say why.
