'sneaking' being the operative word. Obviously the writer has skin in the game (and this is acknowledged up front), but the real issue here is that Yelp is only getting away with this because they're a very established player with a powerful brand that can afford to take the risk of defying Apple.

Mr Galligan is working for a little nothing company that would probably just receive a shrug here on HN if they did the same thing. By observing the terms of their development agreement in good faith, their business model has now suffered relative to the competition. I have no idea whether his startup's ideas/technology are worse, the same, or better, but we're that much less likely to find out now because a more established competitor has (apparently) got away with ignoring the terms of that same agreement because they can.

Good thing Yelp wasn't offering voicemail, eh?
