No, that's the truth. While Maynor knew it was a general platform-agnostic issue, he portrayed it as a problem with Apple and used a third-party wireless card in order to do the exploit. Admittedly, Apple's response was overblown too. They could have handled it better. But Maynor, while being very talented, didn't handle it well either.
Apple later fixed some bugs in wireless, including relating to -- oh my gosh -- third-party wireless drivers. That Apple didn't give any credit is strange, as giving credit is the usual practice.
See my previous post above.
