Some of itโs kind of cool and makes sense. Like developers can get heat maps of where players die so they can see which areas need difficulty tuning, and it can also help developers understand where to spend resources on their games in the future, or notice if players arenโt engaging with something so they can figure out how to make that aspect of the game better. I have mixed feelings about it, but I donโt think telemetry has to be evil.
I agree with your stances but it's widely agreed among people who have to use the data generated that opt-in forms of telemetry are useless because of the way they skew results.
