I don't think this is serious. Hotz's license plate is FUELON, and he runs comma.ai.

There is a difference between critiquing your employer or insulting your employer. Try insulting your employer on Slack or Twitter and see how it goes.
From https://www.nytimes.com/2022/11/15/technology/elon-musk-twit... :
"Several Twitter employees who shared news of Mr. Frohnhoefer’s firing in internal chats were cut, said six people familiar with events. They were told that they had been terminated for “violating company policy,” according to emails seen by The Times."
Is there a difference between "insulting your employer" and "sharing the publicly-verifiable actions of your employer"? Elon's trying to spin this as "insubordination" when in truth he's just trying to quash any and all dissent, like the authoritarian he is.
Quashing such dissent is good and perfectly in line with his responsibility as CEO. Office gossip and politics doesn't serve a purpose other than distraction and disruption - especially when conducted in private chats.
