This is quite understandable - I would not really like seeing Microsoft
use my code.

However, when I was in search for a license for code of mine -Femlisp, a
PDE solver written in Common Lisp- I stood before the question which
license to choose[*].  A commercial license did not make much sense,
because the code was (and is) not yet commercially valuable.  However, I
wanted to retain at least some possibility of providing enhanced value
(in the form of additional features) within a commercial setting.  A GPL
license would make this business model impossible for everyone -
_including me_ as soon as other people would start contributing relevant
portions of code under the GPL.  Therefore, I decided in favor of the
(modified) BSD license.
