Oracle is trying to keep OpenOffice.org going, but only in a certain direction. No one if quite sure what that direction is right now, but I think it's fair to assume there is a definite plan.
LibreOffice, for whatever reason, does not fit in that plan. Or Oracle is worried that LibreOffice is in sync now, but won't be later.
The solution? Invite LibreOffice contributors with OpenOffice.org leadership roles to choose between the two projects, which is exactly what happened last month. This accomplishes two things: those who leave can be replaced by more Oracle-friendly developers. Those who stay will have re-committed themselves to the success of OpenOffice.org, just by staying.
Ah, but there's another benefit here left unsaid: the people who leave--as well as any protesting developers who follow them--will very likely go work on LibreOffice. They will build LibreOffice to be a better, stronger office suite, using better, stronger code.
Code that OpenOffice.org will be more than able to cherry pick right back into their project.
