> replaced nearly nonexistent with irrelevant to make my point clearer

I'm afraid your point is still not clear. What's your metric for declaring a market irrelevant?

A conventional office suite is still the solution which is overwhelmingly dominating the market. Maybe look outside your own bubble and bias. A lot of business will never give away there confidential documents in the hands of third party cloud hosts. (which is the sane approach). So what's your criteria for calling that niche, irrelevant or even non-existent?
