I don't think anyone is saying the game has to offer one thing or another, just that the people selling it should say clearly what it does offer.
Having read through the product description, the FAQs, the developer's forum posts and maybe 30 user posts here on the subject, the best I can make out is that some unidentified number of the scenarios have a programmed AI for at least one side, another unidentified number have an unprogrammed AI, and (maybe) another unidentified number have no AI. So we apparently get some apples, some oranges and maybe some bananas, but it's not entirely clear how many of each.
I think it would behoove the developer to flesh this out a bit in the product description, the FAQs or a forum post. Folks shouldn't have to ferret out these details via word of mouth or, worse, only after buying the game. That's just common sales sense and courtesy.
