I mean, surely federalised social media is the solution rather than the problem here. If you think some monolithic worldview is challenging to welcome new people, then being able to quickly create a new instance for your friends and like minded colleagues seems like a win (hence why the tech behind Mastodon is also being Truth social etc)
Distributed, fully-decentralized is the solution, not federated. Each person should have full control over who they follow, without relying on the whims of server admins.
