undefined> O allows you to be tracked across platforms. There is nothing that ties my Lemmy account to any other account I have somewhere else.
huh? How does it track across all platforms? Your SSO token is completely private, and the lemmy instance can do whatever it choses with it. How can any platform track what you are doing? lol.
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.
