I hope these governments moving to open source can work together and assist in making a more modern and featured open source office suit that has a better UX. I say as someone that almost exclusively uses LibreOffice, it's still a pain to use for anything but the most basic (or esoteric/extreme, like CLI stuff) use cases.
Governments working together to make things better?
I’m glad you’re optimistic but this is something likely up to the individual developers.
Working together doesn't have to mean anything more than providing funding for individual developers.
