I used to think that being open-source was enough to avoid being spied on but it is not. Ubuntu showed this with the Amazon search issue [1] and is apparently collecting telemetry with 18.04 LTS [2]. My understanding is that Brew also gatherings telemetry by default.

Enabling telemetry collection as the default setting needs to end - even if it is well intentioned.
