What is your agenda? What do you have against this guy and his service he's offering? You have other comments that seem negative toward this service or its creator.
Heroku is "just the Amazon cloud", but at a higher price. Of course it offers additional features which some people find beneficial enough to justify the higher price compared to bare AWS.
Likewise, if MoonHome is providing attractive extra features (simplicity, turnkey) on top of Hetzner, then shouldn't it charge more than Hetzner?
In my experience, Hetzner is a great foundation to build on if you're happy with Frankfurt/Helsinki being your endpoints. So this is a plus to me.
