Oracle has done what Sun should have done a long time ago: put OO.org code into the hand of an independent foundation. The good news is that now a wider participation from corporations and individuals is possible. Hell, even Microsoft can now participate into OO.org development. I hope that soon the fork can be reconciled, too.
My first thoughts is that Apache Foundation is a good home for Open Document Format, ODF. If the license will also change to Apache there will be more opportunities to create an ecosystem on top of the standardized format.The free software movement needs a thriving ecosystem around ODF so that we can edit and exchange office documents between computers, mobile and other devices without sacrifices. So far this ecosystem has failed to materialize and OpenOffice.org as a tool has many flaws (bad/old GUI, heavy and in areas like presentation is just bad).
I personally welcome the change as I never believed that The Document Foundation had enough steam in its engine to radically improve the product. But I believe it can still maintain and improve LibreOffice until Apache’s community will start rolling the next generation of desktop productivity tools.
