I don't mind ads so much on my tv (it's a tv after all) as the notion that they will substantively change the quality and behavior of a device after point of sale with no means to revert or refund the purchase. At least when I subscribe to a SaaS and they roll out changes I dislike, I can choose to stop paying them and move to a competitor. Non security updates should always be opt-in.
