This feels like some kind of prisoner's dilemma game theory problem. By defecting from the embargo, OpenBSD gained potential security for its users at the expense of all other users. Overall, this is a loss, unless you use OpenBSD. I have to agree with the researchers on this one; OpenBSD acted selfishly here.
Read that again. We asked to commit without revealing details, he said yes, that's what happened. I guess he changed his mind about that after the fact, but nobody promised not to commit. We didn't "defect" from an embargo unilaterally.
Perhaps "defect" is the wrong word given the circumstances, but the result is the same. There's a good reason for the embargo: this all takes cooperation, as it's not a Nash equilibrium. I still agree with their decision not to include OpenBSD so early in further disclosures, given Theo's short-sighted statement.
It's precisely the correct word. Prisoner's dilemma are simple, mathematically. This was one. OpenBSD defected. The joke's on the security researcher, though, since this doesn't appear to have been their first time [1][2].
Robert Axelrod outlined, in his 1984 classic The Evolution of Cooperation [3] four requirements for a successful iterative prisoner's dilemma strategy. One is retaliating. Security researchers are letting OpenBSD play an iterating game as if it's an N=1, i.e. they're not retaliating. Given the community is playing "always cooperate," OpenBSD's best move is actually "always defect".
So does the simple mathematical treatment also include language like "the joke's on ____”? Or was that more of a philosophical interpretation of yours?
Both your [1] and [2] seem to conclude that violating the embargo had no significant ill effects: "since... the underlying issue was already publicly known, OpenBSD's commits don't change things much." If "defecting" causes no problems for the other participants, does it actually count as defecting? (And if not, how is this a mathematically simple prisoner's dilemma?)
From what I've read, I don't see why everyone is giving you a hard time about this. It sounds like you did exactly what he agreed you could do, and then he changed his mind.
Now that it's more clear what role disclosure deadlines play in cooperating with security researchers, it probably makes more sense to just cooperate than point fingers.
They agreed, but now they regret the decision and wouldn't make it again. To prevent themselves from doing so, they will not speak with OpenBSD until later in the process.
It's a loss, even if you use openbsd. If you break the embargo, you won't be notified in advance anymore. Basically, you get an advantage once but will get several losses for a very long time. Overall it's bad, even for OpenBSD users.
