You can accomplish "no ads" and arguably substantially less tracking without Premium, though, with (e.g.) firefox and ublock origin. The only downside is an occasional ignorable warning that you're "seeing interruptions".
You could possibly pick one channel you like each month and give it a one-time $5 donation, which would be equivalent to years of ad revenue from a single viewer.
Your special kindness is not worth $20/month to even moderately successful creators.
