Class A - no data collection
Class B - anonymized statistics for diagnostics that cannot be used for marketing
Class C - anonymized usage statistics that can be used in aggregate
Class D - Targeted collection that can be used for targeted marketing
Consumers should have the explicit right to opt out of any and all data collection without risk of impairing the primary function of a device. For example there is no reason a TV should need to be anything beyond class A (maybe B). A smart speaker on the other hand needs to be a B maybe C. Nothing should need to be a class D.
