We still see people on social media recommending OpenOffice. Just be aware that it's no longer getting updates, and has multiple year-old unfixed security issues: https://en.wikipedia.org/wiki/Apache_OpenOffice#Security – To be safe, switch to one of the actively maintained successor projects (such as LibreOffice).
@libreoffice I was amused to get a "new" computer at work last December, and the system image included an OpenOffice install from 2019. I replaced that one pretty quickly.
@Doctacosa Oh Please inform your company's IT staff about the risks of OpenOffice!
@libreoffice They also gave me a computer with Windows 10, fully aware that the hardware is not supported by Windows 11. I think I need to start making a list.
