I'm mostly a PC gamer so my view probably isn't what you're looking for... But anyway, Blizzard isn't forcing to to use a third-party program to be able to play games - Valve is. There's nothing wrong with Steam, I just don't want to be forced to use it. Also, Valve isn't exactly 'fair'.
And to get back on topic, I don't mind someone developing exclusively for PC, or for consoles if that's how it's supposed to be. Exclusives are nice, as long as there's a good reason for it. As for developing exclusively for one console only... That's a bit trickier. Some have good reasons, mostly there seems to be money involved and Valve's biggest reason seems to be hate for PS3.
