Once he became the richest person on the planet, he stopped giving a shit. Money buys anything he wants, so why should he.
Honestly, as much as I think he’s a db, and i dislike what hes become, I kinda find it makes him more relatable. I mean, who wouldn’t be consumed by extreme money and power? If anything, it distracts from the idea that you’re a giant cash bag and reminds people that you’re only human. Although from what I understand, he always been this way, and he just had a great PR team in the beginning.
