I'm not completely sure but I think they removed it at some point after the public backlash (which was 3 years ago now). For the Windows version at least, there apparently used to be an option during the installation wizard for setting whether telemetry is enabled or not. Most Linux distros never had the telemetry at all. I don't know about Mac.
Just to know, how do you disable telemetry, if it isn't off by default?
