I prefer the analogy of a fleet of ships - free-traders and pirates alike. Some captains refuse to pass along messages to other captains, and that's alright, because consent should matter, after all, and someone's "right to free speech" does (or rather should) not trump my right to not have to listen to their crap, nor my right if I were a captain to not have to platform it.

So you pick a captain that shares your values, or perhaps you become one of your own.

PieFed has made huge strides in cross-community visibility (multi-communities and combining comments across cross-posts), and in explaining what each instance is all about (see https://piefed.social/auth/instance_chooser), and in migration of whole entire communities between instances.

The Fediverse is not like email. It's like self-hosting your own email server. 🤔😝 But it's getting better. And people will put up with complexity if they see the value behind doing so - it's just that with so little content, and what content there is being so toxic, especially to newcomers, that it's not worth much of a hassle for them to keep trying whenever they hit a hurdle. Lowering the barriers will help enormously with that, as will increasing the level of enrichment to power through.
