> The fact that there is no such thing is strong evidence that they've already hit the economical sweet spot.
This is a simplistic take. First of all, even if it’s true now it does not make it true for all time. Blockbuster hit a real sweet spot for video rental until the tech landscape changed under their feet.
Secondly, and more importantly. Economical optimal for what end? For extracting profits and creating a system where it’s difficult for either side of the network to go elsewhere? Cause it’s not optimized for providing most of the revenue to the people creating the content.
Further I’m willing to bet that most of these services would be significantly technically easier to run if all of the advertising and tracking aspects were stripped out. Which in turn means that it may be possible to architect them differently since you now have different requirements and constraints.
> Nor do you have a right to tell them not to try to prevent you from avoiding that ads are being displayed on your computer.
Correct. I never argued to the contrary.
The thing to keep in mind is that they need us more than we need them. The world existed and functioned before all of these companies and will continue to do so after they’re all gone.
