I'm convinced that no centralized platform is able to provide true free speech and even if it does, people should not be denied of the benefits of moderation/curation so I do think distributed/federated platforms are the way to go, even if they have issues scaling up. True, in the end, they may just end up being bubbles and echo chambers, but you ultimately get to choose which ones to engage in, instead of leaving that choice to someone else and their fickle mood to appease shareholders.
