Products that change the service they offer after you purchase it should also be eligible for a full refund (plus a % on top for the hassle). Such as offering a service through the product for free at the time of purchase but then moving it being a monthly subscription paywall later on, or just removing the feature completely.
Might sound stupid, but perhaps then they shouldn’t be offering services like Disney Plus and instead simply offer a car that lets you download any streaming app you have your own subscription for.
