If Torvalds is trying to engender a culture by being the only one swearing then I'd be very curious where he learned that technique and how he was measuring its success over the many years he's exhibited that behaviour. Occam's Razor suggests that the more likely cause is that he's just an angry man who can't (or doesn't want to) moderate his behaviour.

I don't want to assume too much about your wife's job or personality, but I'd also assume she would swear in a way that was reciprocal with those under therapy, based on a communication style they had established together... as opposed to her swearing at them while they were being perfectly polite.

I was explicitly not talking about the therapy, but the management of the therapy. That's a key distinction here.

In what way? Sorry, not sure what point you're making here.

Can the maintenance of the Linux kernel be considered a success?

Your implication, that this aspect of Torvalds' interpersonal style is vindicated by Linux' success, is a classic Halo effect. Post hoc ergo propter hoc.

I'm answering your question: maybe that's how he measures its success.

So your suggestion here is that Torvalds has some monthly 'Linux success' metrics and varies the amount and style of swearing based on those.

It'd certainly make a good sitcom.
