Apple doesn't use Linux they use BSD and OPENSTEP code and the programs they do use that are GNU they will give source for to anyone who asks. As much as I don't like Apple you can't go after them for violating GNU terms, they have done their work and made sure everything is legal in that department.Funny thing is that someone who worked really hard could sue apple for violating the common GNU agreement by selling a community build Linux. I can not wait to see that happen, the losses would include almost every computer sold by apple, since it all stemmed back from the original case of the GNU violation.
Apple still trying to destroy the competition and monopolize the smartphone market. Aren't there laws against that sort of activity?
