Honestly, this drama every time an instance decides to defederate needs to end. Freedom of association exists. If someone decides they don’t want to be around you for whatever reason, that’s their right.
I just went to blahaj to check their post on this and the majority of people there seem okay with this decision, and those who aren’t are free to go to a different instance.
One good thing about lemmy is that an instance defederating from yours doesn’t affect you in any way. Your content isn’t being taken down and can still be viewed by those who want it.
Isn’t this the whole point of the fediverse? Freedom to choose by yourself what content you want instead of having a central authority decide for you and being stuck with that choice?
Yet every time something like this happens there’s drama. It’s absurd.
