I have a feeling that the Open Document Foundation is going to end up being the loser here. Collabora is the entity that can fund development with a commercial offering. It sounds like they employ the core contributors to the project as well.

Regardless of who "wins," I'm just here to say that I like OnlyOffice a lot better and switched away from LibreOffice. I like that it just looks more like a modern program and overall feels less clunky.
