I think he has focused too much on himself and not enough on the content. He was more worried with building a presence and gaining attention and becoming a celebrity within the small world of exJW content, and hoping to branch out to researching religion and promoting atheism. All of that can be done, but the content always has to be the first priority, and it's clear that this wasn't the case. He relied way too much on others to do the most important work.
And that might not have been so bad if he didn't treat everyone else like garbage. Not paying them (or underpaying) for their efforts, being an obnoxious bully the moment someone didn't grovel enough, picking fights out of a desire to be an alpha male, and so on. And, of course, cheating on his wife with sex workers and melting down on a livestream when this was revealed to everyone. If you're going to succeed with the setup he had going, you have to be fair or nice to at least a few people. He could not even manage that.
Which is why he has almost no hope of salvaging the channel or his 'career as an activist.' Who is going to work with someone who will treat you badly, cheat you out of money, and assign credit/blame in a completely self-serving manner? He has to do all the work himself now. No one else to do it. No one else to lay the blame on when things go wrong. No one to bully when the pressure gets to him. No one to cheat out of compensation. It's only a matter of time, now.
