No you can be angry. It's okay. I was a Mac guy and Halo was going to be my chance to finally have a descent game, which might have opened the gate for more developers to write for Mac. Well we all know how that went. You as the consumer can make the decision on who you buy or not. You ultimately have to ask yourself am I happy with this company and it's product and let your own hard earned cash answer the question by purchasing or not. Eventually the anger subsides and you step into the game and either some Fallen Ai attacks you or you jump on your sparrow and take it for a ride. In that moment you either forgive and have fun and it's water under the bridge. Or you pull the game from the tray and keep looking for what makes you happy.
