Well I guess jewtube decided to roll out anti adblock messages before watching videos. I just got my first message saying "youtube does not allow ad blocking software".
God forbid I want to watch something and not have my eyes and ears assaulted by Pfizer/McDonalds/Disney/etc. at max volume.
If they actually ban adblock I'll just stop using it entirely. It's not usable without it, and it's not worth the hassle to get around it.
There are clients you can use that also block ads. At one point I was using one to get around the "sign in to see age restricted content" crap they pull, because I'm sure as shit not signing in.
