The AI use has nothing to do with this, by the way. The dev can speak for themselves about QA and QC regarding the images they use, but that doesn't justify the user above expecting real art, voice acting, and animated scenes from the developer just because they want it. Bringing up other successful games doesn't have anything to do about commenter's expectations above.
This is simply a means to point out to these types of demands are unrealistic and disrespectful ("...the AI art just ruins it"). The developer can do what they wish with their project, and the users can either take it or leave it.
Show some support and offer constructive criticism instead of tearing down the project.
