He's not supposed to have done anything tangible, at least as far as anyone has shown to be the case. Just some vague handwaving in his direction. There's speculation he's sometimes a bit grumpy and curt, made some jokes about people not wanting to use weak maps and promiscuity in respect of internet connected devices which could be at the root of this, but you'd have to be professionally offended to find issue there. Ultimately these days it seems there are people who go looking for reasons to be offended, or be offended on behalf of others. Naturally, they find what they're looking for. It's a shame this has affected people who just want to discuss technology without prejudice, even if they are javascript developers.
