Another reason to go BSD over GPL unless you really do care about the GNU project more than shipping code & solutions.
But, this is just another prime example of the bizarre logic of Apple bashing. Never mind that Apple does more to give back to open source community than most, lets ignore the facts and bash Apple. Let me give you some more:
Greenpeace bashing Apple even though Apple was actually doing more to reduce environmental impact than any of the beige box companies. Greenpeace's logic was that even though the beige box companies were worse, they had promised to at some distant future unspecified point in time take unspecified steps to at that point be better than what Apple was today... Apple of course said no such thing about their future plans... so Greenpeace was puffing on the vaporware announcement, and bashing the company that was actually taking real steps. Incredible.
Adobe bashing Apple for not putting flash onto their phone - when no other smart phone in the world ran flash... and it would be 3 years before a serious full implementation would come out from a competitor (and lo and behold it was an awful user experience and it killed battery life).

Frankly, as a developer there are an absolute truckload of things to complain about Apple that get ignored, but the ones people pick to focus on are just bizarre.
