Because it's impossible to get telemetry from any source without violating some aspect of the users' privacy.

So you see this as just the same, from a privacy perspective, as the way that the Go tool already dials out to the Go proxy by default? That is, if you're OK with that (I'd assume not, but it is at least existing functionality), you'd see the telemetry proposal as similar?

In other words, I think you object to the Go tool already, so this is really no different?
