Both the Office systems are under the control of FOSS companies, since Oracle gave up their efforts to commercialize OO and left it to Apache.
Michael Meeks, a LibreOffice developer at Novell, compared the codebase of LibreOffice with the OpenOffice.org sources hosted at the Apache Software Foundation (ASF). As he writes in a blog post, the differences are already so great that it will now be hard to exchange new code between the two projects. In light of the several million lines of source code by which the two products now differ, he says users should not assume that code committed to Apache OpenOffice.org will "inevitably and automatically appear in LibreOffice". "Instead I suspect we will end up cherry-picking and porting only those things that justify the effort, as/when/if there is any such thing," added Meeks.
By the looks of it, OpenOffice seems to be reduced to "spear part" delivery to LibreOffice - like a car wreck.
