Why does federated software like Lemmy not use SSO from common providers?

It seems like an easy way to share users across multiple instances without having to deal with actual registration / bots.

... but you don't need to have users in multiple instances. Register once, and use your home instance to interact with any content.
Except until that instance shuts down, goes down, etc. There goes all your posts, history, etc.
Not really. That content still lives on servers with which that instance was federating with.
As opposed to when a large centralized platform (Reddit, Twitter) shuts down, in which case you do truly lose your history.
Large centralized platforms are far far less likely to shut down than small, compartmentalized instances....
edit: Take Lemmy for instance, there's tons of new instances starting up, but many will likely end up shutting down, because the reality is, hosting a service is serious work. Most people don't actually know what's involved in hosting something like this.
The solution for that is simple. Either self-host your own instance OR choose an instance where you can support (with money) the team hosting the instance.
