Telemetry at the OS level bothers me to the point that I'm not Windows user anymore and I I'm not planning to become one anytime soon.

But to be fair one should point out that Apple is also collecting telemetry data (search system logs for com.apple.telemetry) without any toggles in the system preferences.

Search results don't bring much info on what is collected and how it is being used. Does anyone here have insight into Apple telemetry granularity?
