If you ask people what coffee they want, they will all tell you low-sugar, very bitter black coffee. Then you see what they buy, and they keep buying sugary and creamy coffee that contains almost no caffeine.
Telemetry isn't spying. At least when done properly. How do you figure out rare OOM crashes without some telemetry data? What if the reporter doesn't know how to figure out their OS and installed software that's required for debugging?
I'm NOT saying telemetry should capture everything and sell that data to info brokers. I'm saying, done properly it give you valuable feedback. And you should be transparent about it.
