Chromium is open source, but I manage configuration using policies which document the default values: https://chromeenterprise.google/policies/ https://chromeenterprise.google/policies/ It is surprisingly easy to disable telemetry in Chromium as well, and when configuring Firefox using a similar method they send just as much telemetry as Chromium by default.
