I also checked Google Trends for the last 3 months, comparing LibreOffice vs OpenOffice. The first is searched on average 4.7 times more than the latter, which tracks with weekly download numbers.
From those numbers, I'd say it's pretty clear the name "LibreOffice" won quite decisively over "OpenOffice". OpenOffice is still used a lot, but nowhere close to LibreOffice, especially when we add Linux distributions counts.
OpenOffice is by far the better name and has a potential brand recognition that LibreOffice never will.
It was really a terrible name if you're going after normie office workers. Nobody outside of open source people knows what "Libre" means or even how to pronounce it.
