Meh. I just set the environment variable in my dotfiles which opts me out of telemetry. I can't recall a case where MS would outright lie about stuff like this. I.e. with Win 10 they flat out tell you you can't disable all telemetry, and in the case of VSCode they're targeting a real hard-ass demographic, so I trust them to not track me when I told them not to. I also don't use VSCode very often, though.
