I agree with you. I disagree with the assertion from the author that LibreOffice refuses to implement the OOXML standard for ideological reasons; nothing was cited in the article supporting this assertion. If it were true that LibreOffice's developers only want to support open standards, then there wouldn't have been support for the pre-Office 2007 binary formats. Yes, I believe that imperfect compatibility with Microsoft Office is holding LibreOffice back, but perfect compatibility isn't going to happen without massive resources. It's immense work being 100% compatible with a proprietary, under-documented standard. Without an army of developers, it's going to take a very long time. Think of how long it took Wine and ReactOS to get to today's usability, and those projects still have much work to do. Think of how long it took the HaikuOS people to release release-candidate issues of their project.
