Open source conspiracy theorists warn that Microsoft's effort to make the code behind .Net, its software-development framework, open to the public to view — but not modify— is a trap. The goal? It's aimed, they claim, at tainting Mono, an open-source implementation of .Net, with the software maker's intellectual property. And why does this matter? Mono, you see, allows programmers to easily port software meant to run on Microsoft's Windows to Linux and other competing operating systems. But really, might Microsoft's critics be giving it too much credit for cleverness?
