If Apple REALLY wanted to... they'd find a way. No one is truly anonymous. I could be wrong, but when the giant (Apple) really wants to do something legally, they do.
I realize they think they are anonymous - and I also know that they are spread out over a large network, different nations in some cases... but if Apple gets really pisses, they will throw the lawyers out. It only takes one Dev Team member getting their ass handed to them to kinda set things in motion.
Nonetheless, my point is that I'm not sure that Apple sees the Dev Team as all bad... they have undoubtedly furthered how Apple is developing their software.
Disagree all you want - Im not a lawyer
