One of the central ideas in one of Staley Kubrick's masterpiece is to be restored to the film's detail page on Prime Video, after its disappearance caused an uproar.
Not sure how a contact like that would look like our of anyone would sign that. After all, that would mean they could alter your work to whatever. What if they add a swastika to the forehead of someone? I doubt it.
.. what? This is a really weird take. Amazon isn't gonna put random swastikas on stuff. Contracts they have with media companies probably specify in what ways and to what degree they can alter images. I have no doubt they did this legally; WB asked them to change it, they didn't issue a legal demand.
Contracts often have a lot of wiggle room for stuff like this, and the reason life isn't 24/7 lawsuits is because parties with a grievance talk to each other and reach an agreement without going to court and invoking legality.
