Ultimately I think I'll end up running two accounts

I respect if my Mastodon instance decides to defederate because of a legitimate threat from Facebook, given the company's consistently awful history.

There will also be some good people worth following who want to use FB's Threads for whatever reason. If I need to, I can use some special frontend or web browser version to read the content.

So whether we stay federated or not, at the end of the day it'll be ok as far as being able to see things from the people I care about.

In the meantime, I'm going to bring as many people over to the real Fediverse before people get settled into one or the other
