As a thought experiment, imagine what the actual remedy is. An interesting concept would be to break up Facebook using AT&T as a metaphor. Make Facebook open up it's API to allow other applications to connect much like the baby bells could connect to the central network and eventually there were separate interconnected networks.
So the FB feed exists, but multiple apps can post. Each app consumes the feed and sells advertising to their own platform with FB charging a reasonable fixed interconnect fee.

The Facebook API is already pretty open. That's how we got Cambridge Analytica.
