I started using OpenOffice a couple decades ago when I got tired of pirating the market leader. Not wanting to start any religious wars, but I still haven't made the leap to Libre.
It's extremely risky to keep using OpenOffice. Apache has marked its security status as "Amber" with "three issues in OpenOffice over 365 days old and a number of other open issues not fully triaged."
It's also worrying that The Apache Foundation continues to promote and distribute OpenOffice despite unfixed security issues and zero updates to the software. So many people in the FOSS world have called on them to finally retire it, put it in the Attic and keep up a good reputation for FOSS - but they won't do it. It still gets hundreds of thousands of downloads despite being unfixed.
It's irresponsible of The ASF IMO.
BTW, anyone concerned can email apache at apache dot org and ask why they're still distributing OpenOffice despite vulnerabilities. A few people on Mastodon have done that but gotten no answers yet. The more pressure there is to put it in the Attic, the sooner this awful situation will end...
I'd recommend switching, OpenOffice is basically abandonware. There's been security issues that were reported over a year ago that have gone unaddressed. If you look at OpenOffice's git repo (https://github.com/apache/openoffice), the vast majority of the commits are from two people who solely focus on manually fiddling with the code formatting and fixing typos in the comments.
It's so impressively underhandedly sneaky how Microsoft named their ODF-competitor format “Office Open” just as the OO.o hype peaked with OO.o 2.0 having ODF as its native format, when MSOffice finally had a viable and popular competitor for like the first time ever lol

I don't want to start any wars either, but I think people should make informed choices.
By choosing OpenOffice, you should be aware that you are at an increased risk for attacks. One of the consistent problems with OpenOffice over the past years has been that they have often not published security fixes for many months, sometimes critical ones, for vulnerabilities that were publicly known.
(Due to the shared codebase, obviously, many security issues affect both LO/OO, yet, with the difference that LO usually fixes them in a timely manner.)
LibreOffice is vastly more stable and has more features and compatibility fixes that OpenOffice. I recommend using it.
When most OpenOffice devs called Oracle's bluff, left, and LibreOffice was released, I switched right away and never regretted it.
Thanks for the replies re OO's security issues, they're lighting a fire under me to make the move.
