It's harder to join Lemmy than to join something like Reddit; you have to understand the concept of fediverse, choose instance, etc. It requires some thinking and willingness to learn something new.
So if Meta <-> Signal interoperability gets implemented and I have a hypothetical group chat with 5 Signal users and 1 WhatsApp/Messenger user, all the messages would be sent to Meta? I don't like it
It's from 1995, maybe that's why.
Anyway, no problem.
