This goes completely against the principle of "federated network". It's directing new users to join one instance, with plans to expand the list of instances that can be joined through this website to... four. To be selected as one of the four (actually three, since mastodon.social will always be one of them) instances, the instance has to abide by mastodon.social's rules, and selection is done by mastodon.social staff. At what point does "make onboarding easier for new users" become "return to centralized social media except Eugene Rochko instead of Elon Musk is CEO"?
