While I am sure that having the MS-PL and MS-CL licenses approved as OSD
compliant would be of enormous benefit to the projects in question and
indeed Microsoft itself, I don't think that was the actual thrust of the

How does approving these licenses benefit the Open Source community as a
whole, especially given that these licenses seem deliberately crafted to
dig a moat separating the authors and code of the projects in question
from any other open source license or code cooties, rather than building
a bridge?

This is a serious question, even if the OSD-compliance of the licenses
does not hinge on it.
