> Google Docs is a document editor (opening/saving Microsoft office compatible documents, with layout, etc), not a wiki/markdown editor. The La Suite Docs seems a product more similar to Atlassian Confluence.

In the last 10 years I've been spending much more time at the office consulting and editing confluence and web pages (sharepoint / mkdocs / readme and other markdown based resources) than the cumulative time spent on word, excel, powerpoint and pdf documents. I imagine it is the same for a significant portion of the population.

Also, libreoffice is already a thing and nobody edits office365 documents using the web versions except when their employer can't/don't want to pay the license for the full version or the client is not vailable on their OS (linux users). Libreoffice doesn't have that problem, you only really need storage with sharing facilities, not featurefull web clients for your docs.
