The whole point for me moving to the Fediverse was to get away from companies\platforms like FB\IG,and Twitter. Federate all you want with Meta I just hope there’s a running list of which instances does and doesn’t federate with meta so I can join the latter. Not sure why people are so hot on looking at pictures of people’s ugly kids on 2 platforms.
This is why I use a paid host for Mastodon. Six bucks a month gets me my own instance with a custom domain and full admin rights.
There are three of us on said instance, and only two of us are active. It's easier to build a consensus that way. Absolutely none of us want to federate with anything Meta/Facebook. I preemptively blocked threads.net yesterday. To quote Khan Noonien-Singh:
See, that's the nice thing about a federated solution. I can use my personal instance that federates with Mata and you can use one that doesn't and we can both be happy and still talk to each other. Being able to pick an instance that suits your preferences is the biggest selling point of the fediverse.
