John Carmack has a long history working with Apple on gaming products, not all of it positive.
"My relationship with Apple has been long standing, but it's a rollercoaster ride," he told Kotaku. "I'll be invited up on stage for a keynote one month and then I'll say something they don't like and I can be blacklisted for six months."
Carmack thinks the run-ins with Apple are because the company, the highest people in the company, look down on games. But the popularity of gaming on the iPhone has forced Apple to try and come to grips with that, even if they're not happy about it.
"At the highest level of Apple, in their heart of hearts," Carmack said, "they're not proud of the iPhone being a game machine, they wish it was something else."
