You have a very non-standard definition of "Open Source", if the GPL and
LGPL do not fit in, since those are classic Free Software licences!  The
Google SoC rules insist that all work produced under their programme be
Open Source according to the OSI definition at
    http://www.opensource.org/

I believe you are wrong.  Both the GPL and the LGPL (more so the latter)
are perfectly compatible with commercial development.  Specifically, the
GPL and BSD3 (as used by ghc) licences are compatible, in the sense that
you can freely combine BSD3 code with GPL code.  Plenty of people make
money from closed-source projects that include LGPL'd components.

If what you really mean by "open source" is the ability to take code and
into make non-open modifications to it (as BSD permits), then that is
far more demanding than what most people mean by the term.
