This title is beyond confusing, and the article doesn't even attempt to make it clearer. What does "own version of Google Docs" even mean? I took two reads of the article to understand that Proton's "flavor of Google Docs" actually has nothing to do with Google and is just a collaborative document product that intends to compete with Google Docs. The title makes it sound like Proton is offering a reskinned-Google-Docs-in-an-iframe which is incredibly odd.
