He Tweets a lot of simplistic stuff (see: https://x.com/MrBeast/status/1811014883317530846), gets likes, and moves on. Ultimately, he has one goal, and that's making videos. Anything else is just him tweeting ill-informed things.
This would be a consortium of billionaires and/or private equity groups buying TikTok with MrBeast as a PR figurehead. It doesn't make sense to talk about him buying it if he doesn't have anywhere close to enough money.
I think it is more likely that Elon Musk buys it. It fits with his current goals and he is incredibly close to the President. He also has the required access to money/loans that MrBeast doesn't.
