It'll be interesting if any of these "owned by the people" platforms will establish themselves the same way the private social media companies have in the past. Mastodon is probably most successful when it comes to a decentralized platform but it's not the there for me at the moment when it comes to the user base.
You can argue that it's not supposed to be Twitter or whatever but you can't deny the usefulness of everyone being an user under the same address or the wealth of information that comes with being giant. Decentralized platforms have an inherent handicap since there will always be moderation that's up to the admin so every instance will differ in some way (and let's not get to the technical problems that at least here are prevalent). It's harder for companies, countries and other official sources to establish themselves because they subject themselves to moderation of a private third party and jumping from instance to instance, forgoing the extra work it is, is just disruptive and confusing to their audience. They could always start their own instance but that's also a lot of work compared to just creating a Twitter account. There might be some business angle here though but it all just seems too convoluted at least for now.
Maybe internet will be just different and less-centralized in the future. At least it's good that the profit seeking private companies have less power.
