I don't consider any commercial advertisements in my life to be acceptable.
I feel strongly about that, and in general, I'm willing to pay to avoid ads, or to forego things that have unavoidable ads.
As far is the web goes, I've been blocking ads since ~2000 (using Intermute's AdSubtract at the time).
One time I took a plane flight where they began the flight by turning off the in-flight entertainment controls, playing some ads on the in-seat TVs, and piping the audio over the plane's PA system. I wrote to the airline as well as the advertisers to express my disgust for that practice. (Thankfully, that doesn't seem to have become a regular thing since then.)
The only ads I'm subjected to on any regular basis are highway billboards, and I write to my representatives every year or two to remind them that we should ban billboards, or at least hold a referendum so that citizens can decide whether we should be allowing them. (Which I expect would pass overwhelmingly, with a margin like the Alaskan ballot measure.)
So, yeah, that's how I feel about ads.
As I've said, the problem with YouTube Premium is just that it's bad value for my use... if I stop being able to access ad-free YouTube, it's probably cheaper for me to just stop fixing my own things (e.g. I'll pay the dealer to swap my air filters and I'll just throw out the sodastream and buy a new one.) I guess if I ever run into high-value things to fix myself, I'll just churn YouTube like people do other streaming platforms; sign up for Premium, fix my thing, (and save the video, assuming yt-dlp still works) and then cancel my subscription.
