In a surprising announcement the Open Source Initiative said it had approved two of Microsoft's licences as being acceptable for licensing open source software. While many within the open source community will view this as tantamount to allowing a wolf into sheep's clothing, the OSI board (which did not a approve a less permissive third licence) appears to be happy with these two. OSI president Michael Tiemann wrote that the OSI board had approved the Microsoft Public License (Ms-PL) and the Microsoft Reciprocal License (Ms-RL). "The decision to approve was informed by the overwhelming (though not unanimous) consensus from the open source community that these licenses satisfied the 10 criteria of the Open Source definition, and should therefore be approved."
