I can of course write you an answer that will be more than 5 pages long
of why *I* don't think that
Using GPL software is bad for everyone, but I guess that my opinion
doesn't really meter, so I
Won't do it.
The page that you have referenced is of the GNU org, and even there it
is hard to say that they
are trying to encourage you to use the LGPL license. In any case, the
main point is that
When open IB windows was formed there was a general decision that it
will use BSD license. If we
Start having components with the LGPL this will break that decision, and
therefore this requires
some voting of the open IB organization.

Well, the way I see it one can take code from the Linux part under the
BSD licance and use it in
The windows part. The otherway around seems fine to me but some say that
since the windows BSD liscance
Reqires that some text will always remain there, the other way around is
not possibale. As I'm not an
Expert in that erea I don't know who is right.
