They are not targeted (everybody watching the video sees the same ad... for now). They don't invade my privacy. They are usually fairly short. They're usually somewhat relevant to the creator, and therefore my interests. Of course, it depends on the creator. Some have more integrity, others less.
If between Youtube Premium, Patreon, and sponsored segments or episodes creators can make a living, that sounds great to me. Better than TV, radio, or the increasingly expensive and ad-ified streaming services. I'll take it.
