Based off the chatter I see today it looks like Donald Trump's new social media platform "Truth Social" is a fork of Mastodon.
The platform hasn't yet "gone public" (and as far as I can tell, hasn't yet expressed an interest in federating) but some instance moderators are already following the process of blocking federation between their servers and truthsocial.
For what it's worth Tech Dirt and @mmasnick
are great to follow on the topic of decentralized social networks.
Amusingly, it looks like Truth Socials's terms of service will absolutely moderate user content. BuT WhAt AbOuT "FrEe SpEeCh?!"
This Mastodon instance is for people interested in technology. Discussions aren't limited to technology, because tech folks shouldn't be limited to technology either!
