Really? How am I supposed to trust these guys with my data, when they show me a pop-up like that? I guess that this data is anonymous only because otherwise the telemetry would need to be opt-out… oh wait, they explicitly said that:
That said, Fedora Legal has determined that if we collect any personally-identifiable data, the entire metrics system must be opt-in. Since we are only interested in opt-out metrics due to the low value of opt-in metrics, we must accordingly never collect any personally-identifiable data.
