As for not impacting NA customers, maybe you don't know anyone who stays up past 2 am, but that doesn't mean it doesn't impact them. Come Friday night, sometimes one of my only nights to play a decent chunk of time, I play until 3 or 4 or later. I know a lot of people, including various guildmates, who also play very late (or early, depends on your point of view). While I agree it more strongly affected the EU customers, don't discount NA customers who also play in those windows, and remember that are various timezones that are affected so it is not necessarily a simple answer.
