I see open/libreoffice as a shim product the same was as I see WINE. In an ideal world nobody would ever send me a .doc file, but they do so having a way to open it allows me to look to the future without breaking with the past.

Surpassing MS Office at it's own game would probably cost far more resources than Libreoffice could dream of having without having google or somebody throw a ton of money at it.

There are of course many projects that are disrupting office for certain use cases. Examples would be MediaWiki, Wordpress and google docs.
