Nice to see a developer's perspective!Forcing Apple to drop the in-app payment exclusivity will change nothing - hopefully (I don't want iOS cracked open, insecure and not protecting my privacy.)
As a developer I'm happy to continue using Apple's payment system. 15% seems like a lot but it isn't. PayPal takes 6%.
On top of that I don't have to deal with people wanting refunds and users get a better purchase experience using Apple's payment system because it is full integrated into iOS. 15% is worth it I think.
I also think the users will probably convert better with apps that continue to use Apple's payment system because of this.
If they bust open iOS for any payment in-app I won't be switching.
As a user...the way things are now...I trust how it's set up and therefore don't have any problem spending the money. If this goes through and developers make the switch...they won't see another cent from me. I trust the current payment system and it's convenience. Move away from that and that good grace is lost.
Things that sound good on paper don't always end up that way in practice.
