From my understanding, people are not arguing that the Valley oligarchs don't have the legal right to deplatform individuals. The arguments against deplatforming are made in other ways. - Just like users demand feature requests, people who are being deplatformed and people who argue against deplatforming are asking to support a feature called "free speech" and "open communication". - Violation of contract. Users invest in growing the network and influence in these platforms with understanding that "free speech" and "open communication" will be respected. But overtime, the Valley oligarchs like FB, Twitter, Reddit etc pulled a fast one on their users coming up with draconian rules that wasn't originally part of the platform.
