The following I exerpt from the Clay Clairborn piece:

The difference between the GPL and the LGPL is that the LGPL lets vendors link proprietary code to Open Source libraries without making their code GPL. Apparently this is what IBM has done with its WorkPlace office suite. Granted, WorkPlace does some truly innovative stuff for network collaboration, but anyone familiar with Open Office will recognize OpenOffice 1.1--but without credit to Sun or OpenOffice.org. One shortcoming of the IBM approach is that while IBM claims its system is compliant with the OpenDocuments standard, it really isn't, at least according to Gary Edwards.

   IBM is certainly not obligated to contribute back to OOo has no
   legal, moral or technical obligation to do so.  This is due to the
   SISSL/LGPL licences.  I believe also that the way they are using OOo
   components and code may lend itself to making any of their work
   non-applicable to the OOo code base.  I'm speculating here and
   talking from partial knowledge, so please keep that in mind; and I
   invite Gary or others to suggest where I may have it wrong. -sh]

I actually believe IBM's non-contribution to be a consequence only of SISSL, which I gather to have been the license they chose from the dual-license for OpenOffice.org. If they'd chosen to create their derivative work under LGPL, I believe they would have been compelled to provide source just as they would have been if GPL had been in use.
