Do_not_track
Summary
Telemetry is collected by default across many CLI tools and SDKs, with no universal opt-out. The proposal introduces DO_NOT_TRACK as a single environment variable to disable ad tracking, usage reporting, telemetry, crash reporting, and non-essential requests, across all software on the system. The article provides cross-shell examples to set DO_NOT_TRACK and offers guidance for developers to respect this variable and potentially make telemetry opt-in.
