"Anonymous telemetry is more than justified if it improves system stability." - every autocratic leader

Also not "Anonymous" (IP for example or a really good fingerprint about hardware and OS and settings) ;)

It's the old "but it's just the Metadata that we keep"

Except when the browser won't start, and then loses all your previous session, because your internet is out when you start it and so it can't do whatever 'necessary' telemetry and verification it needs.

Yes, just happened to me. Not happy about losing my session. Even less happy about the dependency and what might be being telemetered or 'verified'.

Telemetry is spyware. As such, it is never justified. The anonymous card is for fools.
