I'm not saying you shouldn't complain but on the other hand to me it's like a director complaining someone didn't watch her movie under perfect conditions or a book author complaining someone read the last chapter first.

the game designer sold his idea to his company and then complained the customer didn't use the product the way the designer wanted. it might be frustrating but it's not the designer's choice. the designers choice was arguably not to sell the idea in the first place. once sold it's no longer theirs to control

in general that designer's attitude was forgetting that they had actually gotten paid for their ideas. they took their salary for granted and forgot they had a business arrangement of getting paid for their ideas.

A major difference being that a book reader doesn't say they're doing anything in particular with the book. People hiring creatives, though, very rarely say, "Well, we'll give you your money, but there's a 70% chance we'll fuck you over." Important other differences include exclusivity (readers aren't), amount of time wasted (after the book is published, each additional reader consumes approximately zero author time), type of relationship (readers are consumers; creative employers are collaborators), and expectations of control (which are common for creative workers).

A closer analogy is a film director being upset that the studio didn't live up to the expectations created during the deal negotiation process. That happens all the time with films, and approximately nobody tells directors, "You got paid; STFU."
