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.
Google did the same to GSuite. "Free forever" until it wasn't.
I suppose the whole company is kind of this. Gmail was free email forever, until it got a limit, while people's attachments have been piling up. It's not that it's a bad deal now; it's that it was "sold" 20 years ago as free and permanent. Most people didn't sign up for the deal as-it-is.
