The only part I think I was wrong about was the level of consent requested from the user. I was under the impression that they were kinda like Firefox, opting the user into telemetry sharing by default, making the refusal of data sharing more obtuse or hidden than it should be. But my impression that ubuntu still serves ads and still feels like someone else letting you use their system sounds accurate.
It sounds like you use Ubuntu, so you could probably let me know where I'm wrong.
