There is no controversy: OpenOffice is crapware, use Libreoffice.
The only problem is that Apache still distributes what they are fully aware is an abandoned husk, misleading people like yourself.

It is better not to need to think about that, much.
Does it still work? Sure... is it secure and has feature parity with modern offerings? Definitely not.
Perhaps that's fine - but since LibreOffice is also free and is actively developed (by many of the original OpenOffice team too), I don't see a compelling reason to not make the switch.
