So how correct is this hypothesis?
Ian rose to prominence by dick-riding H3 because H3 had connections to the previous YouTube CEO. With Susan's retirement and death, that took out a huge chunk of H3's influence, and Ian's along with it.
They try to embrace Hasan Piker, who is a rising star with newer media connections, but Ian/Anisa are having trouble fitting in to Hasan's politically-charged group. Then Ian, likely coerced by his BPD Anisa and a desire to fit into a group of radical leftists, decides to shit on H3 because, I dunno, Isreal and joos.
This leads to his current downfall, with them tucking tail and retreating to Canada with a mountian of debt.
