I'm not sure there's much of a consumer market for those products. At least not in the self-operated and self-hosted way you might be thinking. I feel like way too many of us here have major blinders on in the way non-experts or non-hobbyists approach a vast majority of technology and technology adjacent subjects.

Speaking as if I were a layman, why would I download and install a word processor when I can just login to gdocs and have it there?

And in regards to enterprise, you'd be hard pressed to find any tech crew willing to stake their career on open source, user facing tools that don't have a robust support structure in place.
