Honestly I could see this being a way of trapping people by giving them less incentive to leave. If people like us leave and you have to leave the corporate hellscapes to see our posts that gives people a reason to leave too but if they can enjoy it from the "comfort" of Mark Zuckerberg's domain they have no reason to leave. That also makes them captive to met us since they can pull the plug in Federation anytime they like or mess with it in a thousand different ways. Convincing people to sign up for another account may be non-trivial but it's ultimately the best way forward
