It's not a crime, and I use adblockers, but it's not hard to understand that using adblockers on websites which are ad-supported is a self-destructive cycle.
Great, now the creators who's content you enjoy don't get any money to sustain their efforts.
I think letting uBlock stay up as an extension is a brilliant move by Google. It means that the people that use it eventually won't have any content that they actually want to watch, because nobody can make money making it for them.
Sending them $5 via Gumroad or Patreon is worth hundreds or thousands of ad views, depending on the creator's RPM. YouTube ad payouts are pretty stingy.
Watch any popular live stream on youtube and you'll see random people dropping $1-100 at any given time for their favorite creators. I don't really understand the motivation, but is a real phenomenon.
