It’s not clear that smaller sites would have fewer lawsuits if the civil suits were to proceed, as they would be flooded with new users, and with new lawsuits, as soon as the large sites became hostile to them. There are already web3 social media sites that require login with a crypto wallet instead of a traditional user account. It wouldn’t be too difficult to create a site that would be immune to such lawsuits even on a small scale, so I’m not sure why you think that adding more lawyer paydays and violations of the right to freedom of speech and freedom to assemble are the answer. If the site doesn’t want to censor first amendment protected speech on their platform, but the government demands it, that’s a first amendment violation.
