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.
I've been getting these pop overs too. Someone will find a way to squash it, they always do. I will not use YT if I can't block all ads.
