With respect to that, YouTube premium has been around for over ten years, the majority of which I've been a subscriber because adblocking on Apple TV (my primary YouTube experience) is far too much of a fuckabout for me to willingly engage in it, and they haven't yet done it. I think Google is well aware of the fact that Premium with ads is an utter non-starter as a product. What would you even be paying for then? This isn't like TV+ or Prime where you have exclusives, almost everyone who posts to YouTube would happily jump that ship given enough reason to.
And while there are still ads (sponsored segments) I personally have less problem with those since those are substantial money for the creators I enjoy, and a lot of the ones I watch actually manage to make them pretty funny. And hell, a couple I've even used their codes for shit over the years for. Like, an ad is an ad and some people hate all of them, but I can personally say I've engaged with ads from creators I like at an exceptional rate compared to... virtually every other type of advertising I've ever encountered.
