content: Telemetry is pretty common in most software that runs critical systems. An example the Apollo lander sent a continuous stream of sensor data and log data back to earth. There may have been 2 astronauts on the Moon but behind the scenes you had tens or hundreds nerds following the incoming data on their computer screens. Those nerds back on Earth knew something is up long before the Apollo astronauts would know.  Telemetry data is being send from all industrial processes towards central computers that is then used to monitor and control the industrial complex.  Telemetry data sending back is not evil, but what is evil is that Microsoft is doing this behind your back and without consent. This telemetry data is exposing your inner workings of your enterprise, industrial complex, you bank. It punches holes into your enterprise defense mechanism that can be intercepted by hackers and used for breaking in. Before Windows 10, Microsoft asked permission to gather telemetry data so it can be used to improve customer experience. I always pressed yes, because they asked nicely and if it makes the product better then why not?  But when a company does it behind your back, then you cannot trust that company anymore. You have no idea what telemetry data they are gathering. They can literally live stream your desktop, literally live stream your web cam, literally live stream your microphone.
