I don't understand why there isn't an alternative version of Twitter that is as easy to use. The MAGA crowd managed to do this multiple times. But something with the complexity of Mastodon, Discord, etc. won't have mass appeal.

When Trump announced his social network Truth, internet users realized it was a fork of the open-source Twitter alternative Mastodon. Mastodon’s creators have said that’s not legally allowed given Truth’s terms of service.
@shahed The alt-right Twitters are all niche silos that don't have Twitter's success as a destination social media for influencers. So I don't see any success, per se, there. Certainly nothing worth emulating
You get used to Mastodon after a day or so of kicking the tires. The learning curve is a good filter to disincentivize spammers and MAGA while newcomers get used to the culture.
the federated model is superior for a lot of reasons. Topic for later.
