I definitely agree that all things AWS are terrible in terms of learning curve and usability. It's easy to forget how unintuitive setting up static hosting on S3 is (bucket policies, ugh).
So I guess your real competition is either (a) GitHub as that becomes more accessible to non-developers or (b) traditional FTP-accessible web servers. There's definitely room for improvement in both.
Best of luck to you with your launch.
(One of your competitors has a really neat feature that magically makes static web forms work -- https://www.bitballoon.com/. This seems like a great feature that really sets a hosting service apart from a FTP-accessible web server. Making a contact form is non-trivial, much more so than using FTP IMO.)
