Microsoft treats "Windows-only" as open so

mjasay writes: "The Register is reporting that Microsoft is hosting Windows-only projects on its "open source project hosting site" CodePlex. Miguel de Icaza caught and criticized Microsoft for doing this with its Microsoft Extensibility Framework (MEF), licensing it under the Microsoft Limited Permissive License (Ms-LPL), which restricts use of the code to Windows. Microsoft has changed the license for MEF to an OSI-approved license, the Microsoft Public License, but it continues to host a range of other projects under the Ms-LPL. If CodePlex weren't an "open source project hosting site," this wouldn't be a problem. But when Microsoft invokes the "open source" label, it has a duty to live up associated expectations and ensure that the code it releases on CodePlex is actually open source. If it doesn't want to do this — if it doesn't want to abide by this most basic principle of open source — then call CodePlex something else and we'll all move on."
