Seems like a massive distraction from their offering for a small company, wonder why they didn't consider something like tight integration with OnlyOffice or similar. Setting out to build a new office suite feels about as sensible as building a new web browser from scratch. Except at least with a browser, you have open specs helping you through most of the endless supply of compatibility problems.

I don't think they built this from scratch, they acquired a company that did something similar (Standard Notes) and are using their technology to build this.

They can't, all proton products are end to end encrypted, typical solutions like onlyoffice won't work.

For anyone: E2e does not mean 'private'.
