I followed the link and read the article on ieatapples.
I was amused by the part where it talked about how developers are "pissed" at the reminders and camera apps. It pretty much falls into the "competition is good!" category. If they want to keep their apps alive, they need to update their apps with new ideas. Did they think they'd be able to come up with something and just coast on the idea for years? Development isn't a cakewalk, and people who treat it like such, or who got on board thinking they'd be able to make a quick buck, should fall to the wayside and make room for more committed developers.
I admire the guy from instapaper. at first, he was upset that apple duplicated his functionality. Then he basically said "well. Time to start coming up with some new updates and new functionalities." He will do fine because he'll always look to stay ahead of the curve, and those are the developers that are worth buying from.
