I'll quote from Michael Meeks feedback here: https://lists.freedesktop.org/archives/libreoffice/2026-May/094566.html:
"...
Collabora is an Open Source company and all of our code is 100%
open-source.
Also - we have no plans to change the license...
"
So legally it's ok.
About the way to do it, I've cherry-picked locally a patch and going to
submit it.
Don't hesitate to tell if it's ok or not. Julien
