> First, making network requests when downloading packages is necessary for the tool to function and unavoidable.

It's technically not unavoidable. The Go authors could have made use of the proxy opt-in rather than opt-out, making the tool less usable as a result. A similar argument applies here, I think.

> Second, the Go telemetry would apparently create a unique, persistent user ID

Where did you see this? I scanned through the "Telemetry Design" article reasonably carefully and couldn't find any mention of this concept, and the type definition for the posted JSON (the `Report` type) doesn't seem to include any such user ID.

In the end, ISTM that you're not complaining about something that actually affects your privacy in any way, but just the _idea_ of telemetry. Is that really something worth taking such a hardline stance on?
