Yeah I have noticed a few users like yourself (that are the minority, not the majority when it comes to this ) that seem to have noticed that the timing in which he jumped ship from Twitch to YouTube is just far too coincidental, and that he was only buying up some time for his final payment to process and go out with a last hurrah (the begathon) so he could immediately cash in on as much money as possible before he dipped and transitioned completely to YouTube.
Still what kind of gets me is that he didn't have to use some moronic trigger word ploy in order to make it look like Twitch was the villian once again and Phil once again did absolutely nothing wrong in response to this (so if he was intentionally waiting for a moment to get banned, then yes you could argue that this was his final payback at twitch for dropping him out of the partnership program and limiting his precious income making him "destitute").
He could have been upfront and honest with his fans about this and simply just say something along the lines of "Alright guys, the platform that twitch has for me right now is really not what I'm looking for, I'm gonna go to YouTube because that's the best thing for my future and for my community to grow and prosper, I hope you will still support me".
But that's an absolute pipe dream, expecting that much of the the "honest truth" to come out of his mouth.
