I'm big on developer freedom, though I may never know how much of it is actual freedom, and how much is people over developers interfering. That said, they're free to leave out a single player campaign, and depending on the game, I may wish they wouldn't, but if they do, or don't, clearly I don't have to get the game if I don't like the choice, and if I don't like the choice, I may or may not get vocal on the decision, but they still have the freedom.
I.E. MGSPP Online lacking bots, and/or co-op? I don't think I ever want to play online again, but if they don't wanna do it, then I can't make them.
