Given the reality of number of channels who prop up their Paterons and merch stores, and the slim to zero number of channels at any actual scale relying on Youtube, as well as and the constant cuts in ad revenue (how many Adpocalypses are we at now?), not to mention Youtube's hostility towards me as a user, I have no intention to throw Youtube even the smallest bone until they walk back most of the hostile changes they've made over the years.

If Youtube was a platform that clearly cared about its creators, than a 55% split would be pretty fair. Youtube doesn't give a shit about most of them, and if they're just going to be a stupid bytepipe to the viewer, a hostile one at that, then them taking 45% is absurd.
