You miss the point. First, no middle man had been eliminated anywhere, the platforms have simply replaced them with better offers for the consumer right now. Secondly, Doctorow's law of enshittification more or less dictates that once users and content creators are locked in, the tech company will start to deliver poorer quality service and squeeze as much revenue as possible out of you.

So currently, sure I can move around and it is better than the cable companies, but the trajectory of where the platforms are headed is not a good one and trending towards behavior more aligned with what the cable companies do.
