I am still not clear on what constraints it imposes. In the previous system, companies had to either use a copyleft license, or they could buy a license from Sun/Oracle. Assuming they did the latter, and it was in the license agreement, they could do whatever they want in their own version without giving anything back to the open-source version. In practical terms, the only difference I can see now is that Sun/Oracle is no longer restricting things. Anyone can take the software and make their own internal changes without having to give anything back. So I can see how this is a constraint to the open-source community since they can no longer put pressure on companies to contribute back to the project. I can also see how it adds contraint to Oracle. But this seems to remove all the existing restraints from all other proprietary developers. What new contraints are there for propietary developers besides Sun/Oracle? -Todd -- Unsubscribe instructions: E-mail to discuss+h...@documentfoundation.org Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.documentfoundation.org/www/discuss/ All messages sent to this list will be publicly archived and cannot be deleted
