Well, just pay for the subscription. It gives you youtube music as well, and you can share it with several other people. It just a few bucks a month, totally worth it.
Check out the browser extension SponsorBlock which automatically skips over the length of such inline sponsorships (database is maintained manually but does a great job).
Odd take. YouTube has just about anything you might be interested in, in abundance. Even if it is "mostly crap" there would probably still be more non-crap than you could consume in your lifetime.
