Earlier quoted context omitted.
It's just a random reddit post. The OP on reddit didn't even post his game. Three possiblilities: 1. It's just fictional. Probably written by a troll or generated by ChatGPT. 2. Steam refused to publish the game due to some obvious copyright issues (like they told Midjourney to generate superman or one-piece characters) 3. Steam is banning any AI generated assets. My bet is 1 > 2 > 3.
I'd be less sure about that, Valve has taken stances for reasons of public demand and/or their personal ethical standards (depending on what you believe) before, for example the ban on Blockchain games.
"When a game comes up as problematic, it gets flagged a bunch by steam users, and there's a meeting that takes place where they decide if these things stay on steam"[1].
