Give them a few bucks via Patreon or whatever then. That's more benefit than they'll receive from your eyes being assaulted with hours of ads.
And I'm sure I'll get roasted for this but YT isn't free to run either. Alphabet Inc. should get some money from you if you are watching youtube, and I'd rather I just pay them than watch an ad from them.
Minus how big of a cut for google?
