I think the significance of this goes way beyond a conference and is indicative of the fact that due to the NSA overreach, we cannot trust corporations with security the way we used to. Do I think the NSA had some ties with RSA in this matter? Probably. Given Shamir's treatment though by the US government they can't be on perfect terms, but the fact remains, corporations have lost the trust factor. We can't trust Microsoft, Google, RSA, or anyone else.

I think this is the beginning of a major industry shakeup and the word for the ages is "hubris ante nemesis."
