Not parent. The few YT channels that I know of and that produce worthwhile stuff are either unmonetized or can be supported via merch or directly, so no harm done blocking ads.

Especially now that there's ads even on videos by unmonetized channels and YTers who do and share shit because they authentically enjoy it. You know, those that made the site worthwhile in the first place in 200x.

And the mind-crushing amount of clickbait and spam by "professional content creators"? Well, that can go the way of the dodo.
