Actually for many years we have told people "if you want a free alternative to MS Office use OpenOffice". And we told this to people who are not closely following tech news. It's an established brand and it's not easy to undo. Many people will still google for openoffice. It would be helpful if they'd just get a message "OpenOffice is outdated, you can still download old versions, but you really want to get Libreoffice instead".
