When I worked at Microsoft, Legal and Corp. Affairs beat a really
simple rule into people (especially program managers trying to be
helpful):
The license says what the license say.  Your job is not to interpret
the license for anyone.

So yes, it's pretty funny that we're all interpreting here as
non-lawyers.  (IAANAL.)
Lawyers are also notorious for not wanting to set up a body of
competing text to a license or contract.

However, that means there's a specific problem in the context of this
discussion on this list, especially with JonR's original statement
that, "Microsoft believes that this license provides unique value to
the open source community by delivering simplicity, brevity, and
permissive terms combined with intellectual property protection".  If
the Microsoft lawyers presently responsible for these licenses are not
DIRECTLY involved in the discussion about the outcomes they're
considering (or trying to prevent), then you will approve the license
you deserve.

As much as I respect JonR and Bill Hilf, they are not lawyers either.
For this discussion to be valuable, and for the resulting licenses to
be useful and not merely long term sources of confusion, you need to
deliver a set of questions to Microsoft and get the answers OR new
license text under a new revision number if they prefer not to create
competing interpretive text from the lawyers.  The Microsoft lawyers
need to be part of the discussion.

The license's simplicity and brevity are great, but  to fulfill those
purposes developer readers of the license  must not be
[unintentionally] mislead by terms of art.  I remember in early
discussions around similar license attempts inside Microsoft, that as
a casual reader with no formal legal training I completely
misunderstood "distribute any portion of the software" with regards to
how I needed to think about derivatives and the meaning of "the
software".  It was explained to me by the lawyers that "the software"
had clear specific meaning.  Apparently not.
