RMS: «...Their stated definition for the term “open source” is somewhat broader than free software, and thus includes my work. But describing the GNU GPL as an “open source license,” as Microsoft did, is more than half misleading. The GNU GPL embodies the firm philosophy of the free software movement; it doesn't come from the open source movement.

No user of free and open source software (FOSS) can escape having an opinion about Microsoft. Microsoft products and technologies represent what FOSS users have left behind. Some consider it increasingly irrelevant, and others a shadowy figure comparable to Satan in the Middle Ages or the Soviet Union during the Cold War.

Microsoft’s partners team through its NXT initiative launched a campaign focused on open source ISVs in 2007 in conjunction with the Open Source Business Conference. The campaign is designed to encourage ISVs to explore how best to deliver their solutions to customers in the Microsoft world, recognizing that many high profile open source projects have 30%-50% of their installed base in the Windows world. The Microsoft program works through partners to assist ISVs.

It's easy to forget that Microsoft is a software company. Given our near ubiquitous exposure to the Windows operating system (OS), many people don't think of an OS as software in quite the same way as an application - or "app" as it is increasingly becoming known. Of course Microsoft is a software company. What does Microsoft think of open source?

It was with much joy that the Linux community saw two harmful myths about open source get put in their places recently. Myth #1: Linux is bad for business. Linux Foundation: More than 70 percent of work on the kernel today is done by developers who are being paid for their efforts. Myth #2: Linux netbooks have a high rate of customer returns. Dell: No more so than Windows netbooks.

t seems we’ve arrived upon Microsoft open source. In the last couple of years, whenever there was discussion of Microsoft’s open source projects and efforts such as CodePlex or Port25, there was typically the standard open source response: it’s not OSI-approved; it’s not real open source.

Supporters of free software solutions have thrown down the gauntlet at Microsoft's feet. Christian Einfeldt of Digital Tipping Point says 'Sue Me First,' and he's not alone. More and more people are signing up and challenging Microsoft to put their lawyers where their mouth is. The free software community is far from running scared.

For years, the poster child of the anti-open source movement was Microsoft, with its proprietary software model. In recent years, however, the company has changed its views, starting an open source software lab to work on interoperability issues.
