Tracking/Telemetry should always be opt-in. Or at least like:

Do you want to send following data: <Data that will be collected,...> <legalese>:

Big font: NO Small font: Yes

This would be the fairest design for all. Users would be able to make informed consent, vendors get data on a moral good way.

They would just do what most web sites do, and ask users again and again, every day, multiple times per day until the user cracks and irrevocably opts in.
