OpenOffice successfully challenged Microsoft Office from 2002 until 2011. Development has virtually stopped since then, mostly due to low prioritization by Sun Microsystems and Oracle. The Apache Software Foundation took over in 2012 and released version 4.1.5 on December 30, 2017.
LibreOffice replaced OpenOffice as the standard office suite on Linux when Fedora 15 (Lovelock) was released on May 24, 2011. It has been the successor to OpenOffice since then, with over 50 times more development activity. The Document Foundation released version 6.1.1 on August 8, 2018.
Fedora 28 ships with LibreOffice and other "latest and greatest" software, but some users prefer to stick with OpenOffice.
Executing the following commands from a terminal on a Fedora 28 workstation connected to the Internet will replace LibreOffice with OpenOffice:
$ sudo su -
# dnf remove libreoffice*
# dnf -y install gdk-pixbuf2-xlib java
# wget https://downloads.sourceforge.net/project/openofficeorg.mirror/4.1.5/binaries/en-US/Apache_OpenOffice_4.1.5_Linux_x86-64_install-rpm_en-US.tar.gz
