I'm not sure if I understand this article correctly but as far as I can tell, they kinda contradict themselves. While they talk about not collecting anything (which I understand as “we disable phoning home in its entirety”) they later talk about removing the id and still wanting to get the same information as before minus the id. While I appreciate the move, I have two problems with it:

• The headline is imo misleading because while they technically won't track you, they'll still force you to send some telemetry data, leading directly to problem two,
• You'll still not be able to opt-out entirely like, for example, on Firefox

You mean the browser that literally states in their privacy policy that they assign an id to your device and send a ping every 24 hours containing this id and some other metadata including a part of your IP address with which they perform a geoip lookup to approximate your location?
