I mean Musk wasn't as loud about his bigotry at that point, not in the way he is now at least, and Mr Beast has been openly supportive of trans people. Being a bit of an idiot and being a raging bigot aren't the same thing, and that incident mostly convinced people that Elon was an idiot. It's entirely possible he's changed his mind about Musk in 3 years. I'm not a Mr Beast fan by any means, I don't watch his content or anything and tbh I found his reaction to the Jacksepticeye thing to be annoying which hasn't endeared him to me, so I don't have any skin in the game on his end of things, but there were a lot of people who didn't hate Elon after the cave diving thing who do hate him now so I wouldn't really treat that post as gospel personally. A lot of people don't want to admit it but Elon used to have way better PR than he does now, and a lot of people have changed their minds about him over time. So atm I don't see any reason to believe that Mr. Beast would revoke his support for trans people for Musk. His support of trans people is more recent as well. Maybe I'm wrong but I'd rather be optimistic about it until he gives me reason not to be.
