Have you forgotten about Dupee? Come on.
It's overwhelmingly more likely that he'll retcon or "update his opinion" in regards to Twitch if he needs to go back to it, rather than to wait for an apology. Everybody knows this. If that happens, it won't be that much of a shot to his ego because he'll try to brainwash himself into thinking he's being "mature", or whatever other word he uses to convince himself.
On the first month he'll emphasize on giving him tips so that he can
survive until he completes the requirements for Partner, if he actually can.
For that to happen, his Youtube needs to sink, which needs a major fuck up from his part and a decent number of reports (he's actually breaking TOS in his other channel, a report was sent, nothing was done and the content is still there), or get struck through the DMCA in a planned manner for consecutive strikes.
