That's not how you're supposed to think about it. I'm paraphrasing, but ✅️ means "safe" and ❌️ is the shape of your asshole when a known evil corpo entity comes to fuck you.
Fedipact is an anti meta pact that some instances have taken.
Blocked is instances that have blocked meta but aren't part of that pact. Blahaj zone is one of the latter for example. We block threads because it houses hate groups. Were it to stop doing that, we wouldn't block them, but fedipact members still would, because their concerns are to do with what Meta itself represents
I think it's just the fact that they've additionally signed this "pact" that says they'll never federate with them or anything else meta again. See the link at the bottom of the page.
Interesting that most of the top Mastodon instances are fed rested whereas most other software, they are defederated. I wonder if it is due to how they work. Madrid in can have discussion but it's less focused on that. Lenny has more voting and so more likely to have a consensus that shows all views agreement not just the volume. So, Madrid in would be more susceptible to bad actors simplifying their view, yet the same is possible on all.
Doesn't work for me (lemmy.mindoki.com) okay I maybe have only one or two users but still 😅. BTW I had to tilt the phone to get put of the too small "reactive" page so that the search bar showed up.
