Come on, Apache, admit what we all know to be true, and figure out a way to gently wind the OpenOffice project down.
So, it's still being actively refined. I think you're maybe a bit too hard on LibreOffice and Apache.
Also, I'll mention something about Thunderbird. Because Snaps, I installed Thunderbird from the official site. I am amazed by this software. Thunderbird is legitimately a nice desktop email client. What amazing progress.
I wondered about updates for Thunderbird, thinking that since I'd done an out-of-band install, I wouldn't get updates. I was astonished to find it's been silently auto-updating itself with zero drama. Kudos.
This is the key point of confusion! LibreOffice is great, and is the actively developed piece of software for decades now. OpenOffice is just an old zombie propped up by Apache with no actual work beyond the most trivial maintenance and no purpose beyond confusing people. No Linux distro includes it.
