People are just as free to follow diverse viewpoints on social media but for many people that’s not the point. They want that bubble and are determine to avoid it. That doesn’t change with the choice of forum.
Similarly, there’s not that big difference on “policing” - the social media companies enforce very basic terms of service but most people use web hosts with relatively similar terms. The major difference is the discovery mechanism (and the fact checking applied to certain politicians’ accounts which aren’t banned on public interest grounds) which is closer to how search engines avoid sending links to certain sites with bad reputations. A lot of what Twitter/Facebook block will also be dropped by Google or many free web hosts. You can definitely get away with more but I don’t see much reason to believe that it’s a major difference rather than minor variations depending on which companies and content you’re talking about.
