Apple is now threatening to make the same move that Microsoft said they were going to eventually make. They are making parts of the Operating System open source. No doubt they will claim that the whole OS is fully open source, but there is no way that they could do this and keep their business alive. Open source OS users will be very scared of this claim, and rightfully so. There are many people in the world that don't know as much about computers as us, and they will be satisfied with the claim that the OS is open source, even if only part of it is. Right now, Apple cannot release everything in their OS as open source, because they have applications and other types of software from other companies included with their OS, and these companies will not settle for making their software open source. When Microsoft sees that the move for partial open source made by Apple was successful, they will no doubt move in that direction. If this works, it will strongly damage the foothold that open source operating systems and software has made, because the media will interpret "open source" and "partial open source" to be basically the same thing, and cause the advantages of true open source operating systems and software to disappear in the eyes of the consumers
