I don't care when YouTube does a buffer thing because blocking ads for me is about distractions and context switching. My cognitive load is already very high and it's extremely frustrating to have to filter out more garbage.
You could just pay the $13/month? Would save the worries about context switching further taxing your already high cognitive load? And I would expect your high cognitive load helps you earn well above $13/month?
To be clear, you mean it doesn't remove YouTube-placed ads inside the video? Edit: I'm not talking about the creator's own sponsorships, or the YouTube homepage showing static ads for movies or whatever.
I pay for YouTube premium, it absolutely removes YouTube-placed ads. Creators also get a kickback when premium users watch their videos, as they don’t make money off the YouTube ads anymore.
I wish it would also remove YouTube's internal advertising. I pay for YouTube Premium, but I can't permanently hide shorts or prevent it from popping up whatever random topic they want me to engage with. Every 30 days or so, I have to click "Show Fewer Shorts" and every week or two, I have to opt out of the topic du jour, and I have to do this separately on every device.
