Yes, it was quite a good explaination.

... while this is an entirely possible scenario there is little
profit in doing what you suggest so while it is one of the holes
in LGPL it is not really a problem in pratice I think.

No, the problem as far as Wine is concerned, is that somebody might
do proprietary extension of some important part of Winelib that
enough people want so much that most people uses the proprietary
extension and under such circumstances there won't be any incentive
for people to work on Wine.

However, I neither believe this to be true, nor do I believe that
the LGPL will help to stop it other than very marginally.
