One of my OSS bits of software has an XSLX data export options, so I've been interested in the OpenOffice / LibreOffice split because of a bug in OpenOffice causing the file I was outputting to be read as empty. I've changed the file format now, but even for a tech based audience I got a number of questions about OpenOffice.

Just did a Google Trends on the topic [1] and it shows the two surprisingly close, confirming what you say, the openOffice brand still has momentum.
