Do we know absolutely, for sure, that this is what happened? From the revert, bnoorhuis clearly didn't know that Bert had signed it off. To me it looks like there was a bit of confusion, and there's not enough info to say either way. As I said elsewhere, the error bars on this look far too wide.
Given even the remotest possibility that this was a confusion, such a public and childish telling off seems entirely unreasonable.
I appreciate you are an employee and are qualified to speak as such. But as an outsider (and a feminist), I won't touch Joyent with a bargepole after this.
