I’m just saying that Lemmy is a software not a website or service, it’s a bit unfair to assume that everyone running the Lemmy software will host all of the content from different sites, you don’t see this issue with Reddit because no one else is hosting the Reddit software
It’s something we could improve, but I also think that it’s not right to suggest all content hosted on any Lemmy should be visible on every other Lemmy. I mean the users who enjoy the Beehaw community probably aren’t interested in seeing Hexbear content anyways, so this is actually a good feature for them. Each instance admin should have a target market/demographic that they want to appeal to, so they curate their content to match that for the optimum experience for their users.
Similarly Reddit users probably wouldn’t like it if all 4chan content was mirrored to Reddit.
