As an artist your license didn't ban learning from your work. Unless your content was acquired without a license at all - you absolutely gave them permission to use it in training sets.

That is the gap in the legal landscape.

No I didn't. It's use in a software product without my permission. That's never been allowed.

Just because you obfuscate what's happening by calling it "learning" and pretending your model is actually just looking at pictures the same as a human, doesn't make it true.

Unfortunately you did grant that permission. Once you granted the permission for someone to hold a copy, they have the permission to process it.

I can assure you, that you didn't grant a license with an exclusive list of operations that can be performed on your work of art. At best you may have had something like "no commercial use" clause and general broad terms.
