I think there are internal fundemental ideas behind the fediverse that, if protected, will mitigate this issue.

So long as we don't go the way of XMPP who allowed google into their eco-system allowing them to dictate the path forward by being the largest user. Google+ was allowed to federate, it became the largest user pool, and when it changed XMPP either followed or defederated causing users to lose contacts and google+ users to see XMPP users vanishing every so often. All they needed to do was make it harder to keep up than it was worth and XMPP pittered out.

A federated, non-corporate set of platforms won't have the same tendancies as they don't have the same goals, the same influences. If it gets big, and we resist corporations the whole way through, we won't need to fuck shit up for money.

What worries me is that many Mastodon instances instantly wanted to federate with BlueSky. Same with tumblr. So stupid.
