Edit: I made a mistake. I saw that message in this instance: https://oulipo.social/ (the one that was popular a few days ago for not allowing you to use the letter "e") and I believed that to be the default message for a Mastodon instance. Sorry for any confusion.
So, what is gab.ai's story on federation?
"A decentralized alternative to commercial platforms, it avoids the risks of a single company monopolizing your communication. Pick a server that you trust"
It's offering an alternative to commercial platforms, trying to imply that you wanted that. It's implying that you are at risk and at the mercy of a monopoly.
Ultimately it will fail, playing on people's fears backfires. Always play to your strengths.
It's hard for new entrants because Facebook is being responsive to its users. This isn't sustainable over the long term, people at the top will change and priority will shift to short term fiscal returns.

* of course I mean acquired
Indeed, I expect that a migration tool will be developed soon for exactly that reason - it's exactly the paranoia-inducing scenario that will provoke the type of person who runs an instance.
I certainly wouldn't sell my instance.
the innovations in mastodon are how the network is administrated and (arguably) the differences in culture that network federation creates as an alternative to a centralized platform. those innovations can't be copied or bought by a company already committed to centralized administration, which is almost certainly a compulsory thing for a for-profit business.
