That sounds very useful on the non-ad improvements, and oddly enough I might try it for these areas. The sponsor mentions don't really bother me and I just skip them if they're not relevant. Sometimes it's kind of neat to see one and think "Oh, this creator got sponsored by <big deal tech product>, that's cool, get paid!", or if they're sponsored by bs snake oil companies, then I may discount the creator's input a great deal on account of them not having any discernment.

It's a small data point about the content, so it can sometimes be helpful if I'm trying to decide who to pick amongst forty different 2hr lectures on the same thing.

Maybe they accept the bs snake oil sponsorships because they need the money and assume their audience is smart enough to not get tricked.
