Presumably because opt-in statistics are significantly less representative
of the general population than opt-out statistics, since the former biases
heavily towards techies and enthusiasts. My impression is that this is the
primary advantage of FHR over telemetry, the primary risk with respect to
privacy, and the reason it's being communicated so deliberately.
I'm not on the Metrics team though, so this is just my observation from the
outside. Daniel can correct me if I'm wrong here.
