I’m sure someone will correct me if I’m wrong or embarrassingly out of date. LibreOffice was forked from OpenOffice back when Oracle bought Sun because their trademark lawyers were all like “Screw you, we own ‘OpenOffice’ now” to the open source community. Then Oracle realised that owning OpenOffice wasn’t all that valuable when your company’s reputation in the open source community is that of Oracle’s, so gave it to Apache. OpenOffice seems to still have some life, but I think LibreOffice is the one most developers and users have stuck with.
