I also think the 30% would act exactly like a tax on developers: in that way I believe if it were cut or were subject to some kind of sliding scale it would stimulate more activity and bring in more money as almost always happens with tax cutting.

If that was down at or close to credit care payment processing levels up to 10% I think, it would be a no brainer to have subscriptions collected through the app store for things like Basecamp's new email system Hey.
