Saw openoffice on a friend of my father's laptop a while back. it had a 4k screen and OO did not support it, causing every pixel to be 4x the size of other applications, it looked really awful. I told him to download libreoffice instead and that openoffice was not being developed anymore. He thanked me and told me that he had been annoyed by how awful it looks.
I bet if I polled friends and family the ones who know the name OpenOffice would outnumber the ones who know LibreOffice 2:1. And it's only that favorable for LibreOffice because I know quite a few other computer nerds.
so yeah, it definitely happens
