Patreon takes a cut of your money and gives the rest to the creator. Youtube does the same thing with Premium, plus creators receive a higher rpm from Premium viewers than they do from ads. And people left Reddit because they stopped supporting 3rd party apps. Youtube never supported 3rd party apps, plus there’s no suitable alternative to leave Youtube for.
Also, I’m not completely fine with Youtube Premium, but the pros outweigh the cons enough for me to justify paying for it.
Over time I’ve curated the list of creators I watch, so my recommendations are pretty good at feeding me what I like, though I do usually have to scroll through a lot of junk. And when the recommendations aren’t doing it, I’ll just manually go to a channel I like and find something and the algorithm will quickly adjust.
