Chris Tyson had literally been posting erotic pictures of his son since 2023 - he literally posted a tweet saying "Tucker woke up slaying today" and also literally bought heels made for children to put them on his son. If MrBeast wasn't aware of that, that's his fault.
And in case you didn't notice, he also came out as bisexual in 2020 for some reason during his relationship with his girlfriend. That seems kind of selfish to me because if I ever came out online I wouldn't do it during a relationship.
2020 was really the beginning of his downfall
