For context, the author (estebank) is the current force behind the Rust compiler's excellent error messages. To reiterate the lede, so it doesn't get buried: "I’m convinced that rustc should never have the capability to make network connections. [...] When it comes to Rust, users’ machines are (and should be) entirely under the users’ control." (And I don't believe this post is a response or a rebuttal to anything in particular, other than possibly being in the news because of Go. Telemetry was considered for the Rust compiler pre-1.0 and rejected for privacy reasons, and AFAIK has never seriously been pursued since.)
