Except neither Sony nor any other distributor (Netflix, for example) hides the fact that they don’t own the content that you’re paying for and that they have no control over how long you have access to that license - the content owners do.
It’s irrelevant that most people misunderstand the process of buying media. It is clearly spelled out. And I’m not making any legal argument at all. I’m making the contractual argument. With or without the legal system, when you buy something, anything, you’re creating a contract for an exchange of goods or services for money. Sony tells you what you’re getting. They don’t hide anything, as you’re implying. If you still buy it anyways, that’s on you. Claiming people need a law degree to understand something like
“Purchased Content will generally remain available for you to download, redownload, or otherwise access from xxx. Though it is unlikely, subsequent to your purchase, Content may be removed from the Services (for instance, because the provider removed it) and become unavailable for further download or access from xxx.”
is disingenuous. That’s plain English and pulled directly from the purchase page from iTunes. That makes your entire argument here invalid. You asked for understandable language and it’s there. You just didn’t read it or you did read it and bought it anyways without thinking about the consequences of what that means. That’s on you.
Again, I believe they owe you a refund in those cases but that wasn’t part of the contract that you agreed to.
