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.
M$ is no different today than they were in the days of their EEE strategy, they've just fooled the techbros, as you put it, into believing they're still not the scum of the earth anymore.
