I think it might appear that way because there's a pretty strong disconnect between what Blizzard says and what Blizzard actually does. Every single one of their Blue posts in response to something wrong with the game is chocked full of PR sugar coating and spin. Also, just because a design decision was made that doesn't make sense to us doesn't necessarily mean it was based on some dev's idea of fun. It could simply be a a bad decision. Blizzard is not perfect.
Do I think the dev process is completely devoid of influence from devs' person bias? No, of course not. But I think that, ultimately, decisions go through a filter and run up against some basic guiding principles. Why do you think the "no flying ever again" decision was reversed? Because it was pretty clearly costing them money. So they re-tooled it into a more palatable version.
