They're are not charging anything to anybody yet, you can get in the waitlist and answer a survey which explicitly asks if you think the price is to high, fair or to low. Moreover next to the price there's a disclaimer that the "Price is subject to change". To me it seems that they're just running an experiment to determine what's the price they should put to the service, which seems smart and correct.
