Though this data is more or less benine, the point remains. I don't think it's appropriate for a tool like this to phone home, and if it did, it should at least be opt-in, not opt-out (especially considering the opt-out mechanism is something as clumsy as setting an environment variable rather than a config somewhere).

This tool compiles code. Why does it need to make a network call at all? That's going to slow down your builds for the sake of phoning home to Microsoft, a company we don't exactly trust for being good stewards of our information.
