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 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.
