The source code used for programming the system in the machine doesn't mean a thing. It doesn't really matter how many people know the code. The source code is compiled for runtime. There are many encryption programs available for which all source is in the public domain. Knowing the source code means nothing. The only thing this story proves is...people who don't learn some computer fundamentals can easily be provoked by others.
Oh, really? Tell Adobe, AutoDesk, and Microsoft that you have their source code published for free on the Internet. Good luck.
