I don’t have any idea of who they are, but I don’t get it: we’re not preemptively defederating from Meta because it would be closed minded to do so (as per your admin decision), while Meta bad behavior is well documented (they’ve been fined by EU several times already), and we want to preemptively defederate from these people without even knowing how they will actually behave? Why? Shouldn’t they be “innocent until proven guilty”?
I use the XFCE version, it’s around 400 MB idle, fluxbox should be even less I think.
