When Oracle acquired Sun Microsystems in 2009, one of the assets of the deal was Sun's OpenOffice.org software. Adding the open-source office suite to Oracle's already-rich software portfolio looked like a win-win scenario at first. But OpenOffice.org fell to the wayside under Oracle's ownership, which led to community developers splitting off from OpenOffice.org and creating their own spin-off suite, LibreOffice, and development group, called The Document Foundation, in 2010.
With Oracle's lack of support evident and a competing product on hand in LibreOffice, Oracle made the predictable decision to stop commercial development of OpenOffice.org . While OpenOffice.org isn't totally dead – Oracle submitted the code to the Apache Software Foundation for future open source projects – the commercial product is finished.
