As far as I understood from Twitter, the commit wasn't originally signed off.
@piscisaureus signed it afterwards and forced pushed it: https://twitter.com/piscisaureus/status/407022200290410496
What a mess this whole thing is. I'm looking forward to a level-headed explanation of all of this in a few days. It's a pity the witch-hunt happened before there's been meaningful dialogue to find out exactly what the situation is (name-calling and posturing doesn't count as meaningful dialogue).
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.
