Lemmy servers aren’t meant to be “big”. I left lemmy.world for a smaller instance. If the admins of Lemmy.World want to just keep growing and thus increasing their costs, that is their choice. It doesn’t mean all the users need to cough up money. THAT is capitalist propaganda. If the person who runs an instance can’t afford to run it, then don’t run it. You can escape from the system that is stacked against you, the system that demands you pay for every little experience you have, every little resource you use. You do that by giving and sharing with each other and quit acting like a vulture looking for scraps.
Well they only need the content their users are subscribed to, not all content on the fediverse.
