This is good. I know Mastodon would be better, but right now I'm just happy that public agencies are moving away from that far-right platform owned by a fascist asshole who gained global political power because of money...
Its impossible for it to not go to shit. The only way to prevent this is proper federation/account migration, because with those any server will just instantly die from users leaving when they start going bad. Lock-in is the biggest reason for everything wrong with the internet.
Yes. Once a large enough concentration of users is achieved, the network effect kicks in and the users are locked in.
With that amount of users, it becomes a juicy target for businesses who colonize the place to milk said users. That's assuming the original founders haven't already been kicked out and replaced by suits who just invite businesses, influencers, creators, propagandist and so on in and charge them for the privilege. That locks in businesses.
With users and business both locked in, squeeze them for an they're worth until the pain gets too big and the users leave for another platform. Go to step 1.
