>I really hope they recognize the need that people want to keep their data on their lan. Actually that would be required by the GDPR if they won't let me sign anything. My derived data is my own people, it does not belong to who ever collects it.

GDPR is a joke and easily bypassed because users are overwhemingly dumb and agree to anything without reading. By making it online service dependent they don't have to care, the experience will be horribly degraded without signing in.
