> You need one account and then can contribute to all Lemmy communities on all servers.

That's not entirely true, some of the larger instances have no open federation policy, meaning the owner of the instance you are on has to get itself allowlisted in order to federate.

In practice this means that you can follow _some_ communities on _some_ other servers, but not all, and not every popular server.

Add that to the fact that some larger instances have stopped federating with each other and you have the current state; a minefield where your average user tries Lemmy, pastes a link into it's search box as instructed, nothing shows up and goes back to Reddit.
