They are not stealing! Indiana Jones is already out there in pop culture.

We shouldn't complain about AI holding a mirror up to our world and noting "you guys love Indiana Jones a lot. Here's a picture inspired by his appearance, based on your generic prompt that I'm guessing is a nod to the franchise."

The AI is a step ahead of your unsubtle attempts to "catch it stealing".

The image of Indiana Jones is not "ready for market" when it emerges from your prompt. Just like Googling "Indy with whip", the images that emerge are not a commercial opportunity for you.

When you make multi-billion dollar movies with iconic characters, expect AI to know what they look like and send them your way if your prompt is painfully obvious in its intent.
