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.
Youtube's been trying different stuff in recent months. Used to be ads simply didn't exist with an ad blocker. Then videos stopped loading at all for a couple days. Then for a while only the audio of the ad played but not the video. And now I just get a black screen, no audio or video, for a bit and then the actual video starts.
All kinds of sites have tried blocking ad blockers. I don't think anyone managed to keep it up. It's a constant game of cat and mouse and in the end they all seem to realize it's not worth the effort to keep updating their system.
