Telemetry is a strong candidate for my single most hated feature in any piece of software.
The awfulness might be mitigated slightly if it were opt-in and disabled by default, but of course it never is. It is tightly bound to dark patterns.
It's discouraging when open source software becomes infected with telemetry and dark patterns, but at least then there's a chance of forking the project and removing it.
Then layer on all ill thought through corporate stuff and it's not surprising work computers grind to a halt at the drop of a hat.
