Wow, "purchasing a revokable license" is an insane concept. Purchase of something revokable in general feels like... not purchasing? If there was a definite time bound that's one thing, but imagine if I sell a revokable license and then revoke it a week later -- it seems like that would be allowed?

I don't mean to disagree with you, and I have basically no expertise in this area, just shocked by the whole thing.

Would likely win in the UK as we have an unfair terms regulation, a small claims court could easily rule it an unfair as any reasonable consumer would assume they were purchasing the movie to watch whenever they want to.

ISTM there's a good argument for a plaintiff to ask the court to ignore that on the basis that it's a contract of adhesion and one that's effectively unreadable for anyone without a law degree. We're not talking about terms and conditions that fit on a single sheet of paper in a normal font, bu thousands upon thousands of words.

Tech EULAs are just absurdly long, and I'm sure they've expanded since this article was written in 2020: https://www.visualcapitalist.com/terms-of-service-visualizin...

No, that is not what the plain meaning of “purchase” is.
