Flatpak top contributor by number of commits works for collabora, so i think it is a matter of just getting funding for work. no need to start an ugly fork. its a question of how badly people want the work to be done.

I wonder how well collabora would do if they started a subscription for regular users that could vote on what issue to work on (and maybe delegate their voting power), the issue that he mention that is “not great” sound like something a lot of people would be interested in fixing. and in general with so much of our lives documented on our computer more security enhancement work could be great.
