Mastodon is interoperable, decentralized, operated by a nonprofit, lively, and, ACTUALLY, isn't hard to use. So why is everyone championing Threads as the main Twitter alternative?
I can move to another Mastodon instance, and keep following the same accounts.
You can't. What you can and can't follow is determined by whatever the server federates with, which is not under your control. Also you lose all your followers and in case of server shutdown all the accounts on that server stop existing, so you can't follow them either.
Federation is a brittle framework that starts collapsing the moment anybody tries to use it seriously.
Dumb analogy.
