New restrictions that Apple added to its iPhone software developer kit (SDK) have led an independent programmer to cancel a conference devoted to Mac programming and computer science, according to a “CNET” report (http://news.cnet.com/8301-30685_3-20004869-264.html).

Jonathan “Wolf” Rentzsch announced Wednesday in an online post (http://rentzsch.tumblr.com/post/592949476/c4-release) that he had canceled the C4 conference after four years organizing it because of new wording in a section of the iPhone OS 4.0 software developer kit.

He wrote: “With resistance to Section 3.3.1 so scattershot and meek, it’s become clear that I haven’t made the impact I wanted with C4. It’s also clear my interests and the Apple programming community’s interests are farther apart than I had hoped.”

“… By itself Section 3.3.1 wasn’t enough to cause me to quit C4. I’ve weathered Apple lying to me and their never-ending series of autocratic App Store shenanigans. But unlike previous issues such as the senseless iPhone SDK NDA [nondisclosure agreement], the majority of the community isn’t riled by 3.3.1. On this issue, Apple apologists have the loudest voice. They offer soothing, distracting yet fundamentally irrelevant counterpoints to Apple’s naked power-grab.”

Central to the matter is the ongoing brouhaha over Apple banished Adobe Flash from the iPhone, iPod touch and IPad. And Apple has restricted even native applications originally written in Flash with new wording in section 3.3.1 of the iPhone OS 4.0 software development kit, notes “CNET.”

C4 was a Mac software developers conference held in Chicago, Illinois. The conference ran from 2006 through 2009. It was created by Jonathan Rentzsch after the demise of MacHack.
