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. 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.
