A user has noted that Gnome-shell/gdm connects to some gnome servers on login. As expected, it’s turning into a discussion/speculation on security/privacy/what have you.
Could someone that knows what this is please chime in to clarify:
I think it’s the gnome-extensions update checker bit, and I’ve noted this there, but I’m not well versed enough with the gnome-shell sources to be sure. If someone could please add a well explained authoritative answer, that would really help
