Microsoft Launches OSS Site, Submits License For Approval
prostoalex writes "Microsoft has launched a site dedicated to collaboration between Microsoft and open source community. The site helps developers, IT administrators, and IT buyers find out what Microsoft's product offerings are, and read articles about open source such as 'Open Source Provider Sees Sales Doubling After Moving Solutions to the Windows Platform.'" Relatedly, CNet has the news that the company has submitted its shared-sources license to the OSI for approval.
FOSS != OSS
See the Wikipedia article on Alternative terms for free software and RMS's Why "Free Software" is better than "Open Source".
I think a better list of things to consider is whether you have freedom to (1) use, (2) share, and (3) change the software. If you can do all those then it's free software, no matter which company it came from. There's no reason to hold Microsoft-written code to a different standard to other code. If it's free it's free.

It's a reciprocity clause. Suppose A holds some patents, and they've contributed them to software S and licensed them for use there. Now, B comes along and sues everybody using software S (including A) claiming that it infringes some other patents held by B. If B uses S themselves, the clause is intended to insure that B loses their license to A's patents, opening them to being counter-sued by A for patent infringement. The idea is to force a situation where a patent-holder can't block everyone else from benefiting from a piece of software while continuing to benefit from it themselves.
