Could Adobe be considered as creating it due to them generating AI assets on their servers in the cloud and not allowing users to do it with their hardware?

Unless I missed it, I don't see anything here about the assets being created using Adobe's AI services. Unless that is a requirement of Adobe Stock?

It seems like there are 2 distinct problems going on here. The fact that this is on Adobe Stock in the first place, which is questionable even if it was a legit image.

The second being it generated by AI, which is unclear what services made it.

But is generated by Adobe? The picture is being sold for $100 which seems weird when you could just generate the same on the same website for free
