These content agreements would have end dates when they are negotiated so they should be required to disclose those at the time you "purchase your license".

If they renegotiate and extend the arrangement then update the UI with the new date.

Sony couldn't seriously believe they were going to be able to renew these licenses forever given how many streaming services are out there who need to fill their catalogues.

Instead it's better for sales to show a "buy" button with no date[1] so customers don't back out when they realise they'll be spending close to the retail purchase price to only rent it for a few years.

When the legal reality does not align with actual reality, there is injustice of the worst kind.

The button says "buy" not "rent" or "license".

That should be enough to defeat all the fine print, click wrap hidden clause clever maneuvering bs. The merchant is lying to the buyer. The merchant should bear liability for deceiving the buyer. The merchant (Sony) knew what they were selling. They lied to make it seem like you'd have that video in your library forever. Sony needs to give a refund with interest. Simple as that.
