Private companies’ freedom to define how their platforms are used should depend on the “private company” growing out of its niche and becoming what’s basically a public utility, a railroad owning one of the very few means of information delivery. Then, I think, different regulations should apply. I don’t know how this is going to be implemented in real life though. We clearly see that Twitter and FAANG have power to shut down such attempts and even more so after entering a mutually beneficial symbiosis with certain political groups. It’s hard to see where this is going.
