Oh look, it's the talk where Theo blatantly and shamelessly pretends he invented all of the mitigations that Spender and Pax Team had many years before anyone at OpenBSD even mentioned it. They pioneered stack randomization and ASLR? Are you serious?
Aside from OpenSSH, OpenBSD is not security relevant, and hasn't been for about a decade. So when they don't get the 20k, nothing of value is lost.
I just started watching these. About six minutes into the fifty minute talk Theo says "this wasn't our idea." If he's trying to convince people he invented that idea he's going about it in a subtle, reverse-psychology way. (he's not)
