For some reason developers think they're magically exempt from judgement of their data harvesting. I don't want you monitoring my activity on my goddamn devices, however much you yammer on about having good intentions. The act itself is hostile, and that's why developers are so goddamn sneaky about it. You're invading privacy and creating metadata records that are trivially deanonymized.

There's an honest, non sneaky way of gathering usage information: pay for rigorous testing and price the cost into the product. Telemetry is lazy, invasive, and user hostile by default. Every bit of information acquired from users should be given with informed consent or not collected at all.
