It's possible I've let myself develop too negative a knee jerk reaction to the idea of telemetry. Sometimes I've lost a feature I use in a product that I'd turned off the telemetry for, and the developers cited low usage of that feature. Did I shoot myself in the foot?
I figure that if the devs are making decisions about what features to keep or drop based mostly on telemetry signals, that alone is enough reason to avoid using the software.
