I don’t see the similarities. They’ve sold an annual subscription to an advert free streaming service. If the service is no longer available then they should offer a cancellation and pro-rata refund.

Actually nowhere does it say in the Amazon literature that Prime (video) is completely ad-free (the live streams definitely aren't). It just always has been for the library content and you can buy extra stuff/channels through Prime. But you don't get those included and you never have done.

When you pay for Prime, you're usually buying it (by accident or otherwise) when buying something. So its always been seen (and was launched as) free shipping for £x a year, an offer which has had just bells and whistles added over the years.
