You're breathing air. I own all the air. Pay me.
Now, if I claimed this seriously, most people would laugh me out of the room. But some might not and actually pay up. Especially if I threatened to sue them if they didn't pay up and the "I" was a big, well-known company.
What Getty does is not just muddy grey misrepresentation, it's outright fraudulent.
- They say it's copyright infringement in their letter. It is not.
- They say you need a valid license to use the image. You do not.
- They demand a license fee. Not a "you used our service to find and download this public domain work" fee. A license fee.
- There is no indication whatsoever Getty/Alamy had any role in how the photograph got onto the website of Highsmith's foundation. Given it's her own photograph, it's unlikely she used Getty at all. But they do not claim a fee for using their services anyway, they claim a license fee based on copyright law, which they cannot.
Highsmith gave up her copyright and cannot demand attribution or damages under the copyright law, so I agree with the court there. What she instead should have done is file a criminal complaint and a civil suit regarding the attempt to defraud her.
