That is a good point. But I usually pay through Patreon. I wonder which one is better, and if I can attribute YT premium to a specific author?
Your argument only makes sense if you watch the creator's videos exclusively on Patreon (paid by the cut they take from your transaction) or on a platform like Vimeo (paid directly by the creator for hosting). In which case, what Youtube does isn't relevant to you.
e.g. Linus Tech Tips posted up their share of revenue from AdSense in 2024; YT Premium made up 37% of their revenue despite being 29% of their views.

Whether that makes a given creator more money versus Patreon depends on how much you watch them, frankly.
