It’s not that bizarre. They don’t have to serve you the content without showing you the ads that make the platform profitable. The freedom goes both ways. I use an ad blocker too, but I don’t think that YouTube is really doing anything wrong here. (Other than possibly ruining their own platform, but that’s their problem that they’re making for themselves.)
If they weren’t a monopoly, I’d agree, they can do whatever they want.
But since they are a monopoly, its a de facto the equivalent of a town square, and they are policing people’s speech, and broadcasting annoying public announcements that nobody wants to hear.
I hate the way they‘re doing it and how they push their silly premium subscription in my face whenever I open the app to look something up quick. Adblock all the way. But you‘re right. They have to make money somehow. They‘re a corporation after all. It‘s naive to think they will ever give up.
