Also, these users don't even know which instance to go to, since there is little to no-one to talk on there. If there are 'hundreds of thousands' of users then that means they have just recentralized on Mastodon.social, the "main" instance, defeating the point of it all.
> PS. Please do not say anything about “anyone can start his own instance”. No, average Twitter/Facebook consumer can’t start his own instance.
This is why Mastodon has failed in the first place after almost 6 years with this system.
