From my research, Patreon takes a smaller cut than YouTube Premium. Comparing YouTube Premium to its own ad model is a "Worst Negates the Bad" fallacy. From what I gathered (not easy to find and has changed over time) YT takes 30% from the former and 45% from latter. Seems insanely high. More than taxes. May be why so many creators need sponsors and hawk merch.

YouTube never supporting 3rd party apps seems like a negative.

Lots of suitable alternatives to youtube: read a book, listen to music, go for a walk, hang with friends, play games, etc, but to your point, sounds like a monopoly. Their search was once great, then ubiquitous, now terrible. YouTube Premium is just in the "entice users and creators" phase of its inevitable enshittification.

Don't mean to dump on something you like, just disagree with the reasoning. If you're not fine with Premium and hate giving money to google, sounds like you'll eventually seek out alternatives when they go into profit maximization mode. Hopefully enough resources will have been invested in viable alternatives by that time.
