The Free Software Foundation is petitioning Microsoft to open-source Windows 7. That sounds crazy. Until you really think about it.
“We call on Microsoft to release Windows 7 as free software, and give it to the community to study and improve,” the FSF petition reads. “As there is already a precedent for releasing some core Windows utilities as free software, Microsoft has nothing to lose by liberating a version of their operating system that they themselves say has ‘reached its end’.”
