Last I saw, Google charges for this. More than this guy’s service.
Also, it seems like his service is about automatically having username-category email addresses. Definitely not hard to replicate, but it circumvents the common blocking of plus-signs in email addresses you see nowadays. And while not hard, it’s a bit less trivial to catch any old email with a dash in it and “magically” convert it to a category in the main inbox.
