You can think of it like emails.

A lemmy community is like an automated mailbox that sends everything they receive to all subscribers.

You can host a mailing list/community on gmail.

Then you can subscribe to the mailing list from outlook.

Then a user can send a post to the mailing list from yahoo.

The automated mailbox at gmail will receive the message from yahoo and send it to outlook and all other subscribers.
