Well it depends what their target market was. If you are going for "traditional newspaper readers", betting that tablets will replace paper over the long term, then I can't imagine stuff like "single click" to matter. I for one don't think that anyone having a physical newspaper subscription right now would change to a different newspaper because of this...

Of course that demographic is going to disappear and all huge newspapers have financial problems at the moment. But for example the NewYork Times web subscription has >500.000 paying subscribers... I don't know, paying 30% to apple for a better payment gateway seems just excessive to me.
