Web Brower with ad-blocking setup can still have advertisements leak through. When it does and it still does after three refreshes, I just don't watch and move on.
I will always be a sunk-cost for Google.
I find being advertised to so annoying there's no way in hell I will spend my limited time on this planet willingly consuming an ad.
Watching ads simply isn't something I'm willing to consider. Like if the transaction was "have someone spit in your face and in exchange you get a how-to video and they get paid based on the amount of spit you get in your mouth", I'd feel similarly about that business model.
Really how do people put up with that shit??
Having said that YouTube is so enshittified in other ways too (screaming thumbnails and titles, sponsors which need sponsorblock, random AI clickbait videos) that I rarely feel like watching it at all anyway.
I tend to skip those, although map men's are good, but I also tend to prefer those who don't have ads.
I never had genAI tracks being suggested on YouTube Music. Though it might be a factor that my account predates genAI music.
I assume one requirement for getting genAI tracks is being initially fine with hearing music from random channels and also hearing music produced after 2022; if one only cares (for example) about pre-2020 very well-known music they're probably going to be safe.
