(I am the author of the comment in Reddit) AFAIK there is no instance of lemmy in fosstodon.org and there is no FOSS-only-purpose server in Lemmy.
I agree perhaps lemmy.world server is one of the best options to locate the community due the size (size is important in the fediverse because higher servers are supposed less tending to disappear or to have funding problems) (https://lemmy.world/post/579472) and as @[email protected] said it includes the lemmy word. However, so far, there is no way to migrate one community from one lemmy server to another one and the only solution would be to create a new community in a new server and remove this one to avoid confusion (there are few posts so I think is a good time to do it).
