This was maybe 5 or so years ago, but I remember Game Grumps did mention something along the lines of how they get more from someone watching their video on YouTube premium vs someone who watches their videos with ads playing.

It's still not a ton of info, and I'm not sure if it's still true. Or maybe it's different for every channel or something.

That's why I still use Vanced. Sponsorblock is something I can't live without even though I have YouTube premium.

That's not feasible if you upvote a lot of stuff. There's a difference between, "let me upvote this so it gets visibility and to help there be activity on this site so it can grow" and "This has a piece of information that I want to look at later when I need it."
