Pity they want money to access the doc. I've spent years on a distributed, zero-knowledge sync service so would love to see what they've done. I should probably add the polish and make mine public, because as per the article I also feel this is the only way we'll ever get past the centralized giants. My test app is a document editor where multiple people can make and sync up changes to a shared doc without leaking anything, i.e. what's in the document, that it's a document, who they're collaborating with. Of course the client will be open source. It won't matter if the server is closed source or not. Not going anywhere near a blockchain with mine though, because if a user wants to delete a thing (anything that user created, including the user's account) it must (and will) be deleted.
