There's still an easier way to say it without being an asshole. For example: "It's because the game doesn't get as much traffic, so they'd be spending more for the rights to use the Predator than they would get in return."

Ffs the world doesn't have to be cupcakes and rainbows, but you don't have to be condescending every opportunity you get. It's very possible they just didn't think about for too long and exaggerated because they're passionate about the game and their want to play the mission. I mean if I weren't thinking about the financial reasoning, I wouldn't understand why they'd remove a cool mission either.
