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.
