We can only hope he does. More people move over to mastodon with large companies running their own instances in the ecosystem.
This would allow for a federated broadcast system similar to how Twitter is now used, but if mastodon gets critical mass and governments start using it like they do Vichy Twitter it would be great news.
If that leads to some extra government grants for the further development of mastodon and the fediverse… Possibly even under the guise of standing up to big american tech… we all win.
But if he does, he signed the Death warrant of his own platform. A lot of governments and mega corps are there because of users. Governments will all need to replace it immediately if they find out their main broadcasting platform could be turned off tomorrow.
