This is is a clear cut case of a game being pulled because the publisher no longer has the rights to the licenses involved, which is generally why this happens. Publishers usually won't just pull a game all willy nilly. It's not a good idea for you to suddenly stop selling your games, because that caps how much money you can ever make off of it. What would you rather they do? Just silently remove the game from the store and not give anyone the chance to pick it up if it interests them? Or should the publishers just slowly bleed money away on maintaining the licenses for the IP therein for eternity? Or better yet, make no video games that aren't original intellectual properties? There's no clean solution to this issue.
