"Somebody toss me a Che Guevara T-shirt. Google and Microsoft have gone to war over open source software.
On Aug. 10, Redmond submitted the Microsoft Permissive License to the Open Source Initiative (OSI). Should the license be approved, Microsoft would receive the "open source" seal of approval that only the OSI – by self-proclamation – can okay.
Many open source watchers have applauded Microsoft's OSI approach. You'll remember that Microsoft has dubbed some open source software the work of cancer-ridden communists. So, seeking "open source" approval shows the software maker has come a long way."
