Doc getting caught cheating is old news. His family already almost disintegrated because of it and he had to take like a year off to mend his relationship with his wife. So if it's related to that he's good with the family, his wife already knows who he cheated with etc.
We didn't know who it was with.
Idk if that would really be enough for Twitch to cut off one of their biggest cash cows and one of only a handful of streamers to sign an exclusive contract with them. I feel like it would be more serious than just breaking ToS. Especially since they've known for a very long time about this (I mean he broke the viewership record on his return stream from his break over cheating. even opened it with his wife holding a knife to his neck to keep him in line
)
It would be weird to me that they'd allow this girl to blackmail them over a raise for something they all knew already. There has to be another layer to this. Or it's something completely different.
