Also, this incident seems like a net loss for PR, so it being a strategy for more donations doesn't really seem to make sense.
There are PR upsides: the shephard protects his flock from the unspeakable danger; it makes for good drama and folklaw; there's opportunity for further drama caused by leaks. Also, it shows everyone who's the boss.
A popular motto claims that there is no such thing as bad publicity.
Firstly, if there's an unspeakable danger, surely it'd be best to try and not let others be exposed, so this one's really a question of if it's dangerous, and not an argument in itself. It's only a PR stunt if it's not dangerous, if it's dangerous good PR would merely be a side effect.
The drama was bad IMO. Looks like bad publicity to me.
I discredit the PR stunt idea because I don't think SIAI would've dumb enough to pull something like this as a stunt. If we were being modeled as ones who'd simply go along with a lie- well, there's no way we'd be modeled ...
Some research says that lurkers make up over 90% of online groups. I suspect that Less Wrong has an even higher percentage of lurkers than other online communities.
