I know just about everything I could ever need to know about both companies and I have tons, tons of friends who absolutely love and have been at "M$FT" for 5-20 years.
I don't know a single person who likes working at Tesla or SpaceX and I used to live in Austin.
I'm also a literal linux kernel contributor so I don't have any bone in the game for Windows.
Musk is literally spitting right-wing nazi, anti-trans trash all over twitter and using his new news medium as a right wing mind meld tool while unbanning known anti-semites and racists like Kanye and Trump. Cool guy. I guess you might not care about that when you're a middle-class straight white tech bro on hackernews and might think M$FT is the big bad guy because Bill Gates locked you into Internet Explorer and adware 15 years ago.
