Attempts to contact external telemetry servers under default configuration is the issue. That not all of the needlessly locally aggregated data would actually be transmitted is separate.
> Telemetry is perfectly acceptable as long as it is opt-in and does not contain personal data, and both apply to Go's telemetry, so there's no need for a fork.
This changed somewhat recently. Telemetry is enabled by default (I think as of Golang 1.23?)
