It’s the same reason there isn’t a central email sign on. Different people control different servers. They’re all just using the same protocol so they are interoperable. Just like your email, you have an address that points to your particular account on your particular provider. Name@host.tld. It’s essentially the same thing as email, just a different form of interaction.
I understand why there are many servers, but why is there no central single sign on for many servers? Same with syncing community’s over instances.
I’m new so not sure why or why not.
