I was actually curious about that whole situation since it's been so long and went to go brush up on what actually happened, here was his statement after WWE fired him
So he took the pic Hitler mustache shaving pic (can't even count how many movies or tv shows were making this same joke at the time before we realized it was pretty fucked) in 2015. He was apparently being threatened with it getting exposed 5 years later so that's when he sent it to his ex to ask her for her help on how to handle it
Then a few years later she extorts and gets him fired with the same picture, I feel so bad for how funny I find that
Also seems every bit of abuse allegations were either proven false or recanted by her. She straight up just got him fired out of spite
