> Recording information about someone's computer and then sending it to the developer without their knowledge or consent is spying.

That's why I said done properly. You need full transparency. What is recorded and why, and how is the information dealt with.

In practice most people don't care. If they did they would disable all achievements, because even achievements are a form of telemetry.

You can see what percent of people finished the game for example. What percent played mini game, etc.

Anything that reveals remote metrics, is telemetry.
