The text is clearly human made, and altogether the whole thing is funny. The tool for creating the images in this context doesn't really impact upon the quality of the work as a whole given the low standards and the fact that it's literally a joke, and furthermore is pretty unlikely to have put anyone out of a job. I can't imagine anyone is making a profit out of this so even the murky topic of copyright for the training data used by the model is at the very least less bad even if not completely abrogated.

If they'd done this with stolen images from the web and Photoshop I don't think there'd be a lot accusations of 'Photoshop slop' because they didn't create costumes and props and do a shoot on location and went with the 'lazy' option instead.

There are many things to be worried about with the popular availability of generative AI tools and the torrent of slop that's being pushed out of them but this really seems not to be one worth worrying about or even having contempt for.
