Most telemetry is more along the lines of "user spent N minutes on platform, clicked on these things, looked at these other things" etc etc. And the primary way devs use this data is by aggregating across all users and running a/b tests or viewing longer term trends.

Are some companies spying on you the way you say? Yea, probably. Most of us just want data to know what's working and what's not.
