Quoting the FediPact:
Openness for the sake of openness is meaningless. Two things that are very valued on fedi are consent and freedom of association. The whole point of the fediverse is that instances are free to choose who they talk to. We don't have to federate with the likes of gab, for example. Growth for the sake of growth is the ideology of the cancer cell, chasing a capitalist pipe dream
I wanna give it a try, but I've been looking at the servers and I haven't found the one for me and what I'll use the account for. Nor do I know of any account on a pixelfed server I could be interested in following...to just follow accounts on completely different federated servers it wouldn't make any sense to me.
