I don’t think making art in the style of a copyrighted piece of work is wrong. Like writing a fanfic in an existing world (Harry Potter, LOTR, Blade Runner, etc.) isn’t copyright infringement, it’s covered by fair use. I think Alcon are suing the wrong person. A better case for copyright infringement is the AI company who trained their AI using copyrighted material that they almost certainly did not have permission to use.
Remember when Microsoft said Windows 10 would be the last version of Windows?
