Yes, but there is a huge difference between email and social media - namely the community. You don't have that in email, so changing a provider is as simple as "my email now says @gmail.com". For social media, you need to "migrate" an entire group of people and the content that was present on a doomed instance. Which never happens. It's never seamless, it's always the "same" community with no history, different moderation, server, with different people. Don't get me started on two communities about the same thing, on two different servers, that don't know about one another.

Fracturing the lifeblood of your "forum", "community" - your users will end up making decentralized frameworks / social media less popular than large centralized ones - no matter what you do.

changing a provider is as simple as

making sure every single account you had that is tied to your email now points to a correct new one. And also informing every one of your contacts of the change, which is easier but also less efficient since half of them is going to miss the announcement and keep writing to an email that no longer exists
