*Edit: Thanks to rome's comment http://news.ycombinator.com/item?id=2286805 and reading Red Foundry's page a bit I understand the app a bit more. It seems to be for testing your (Red Foundry) apps, not downloading other peoples apps. Seems to me that these test apps are intentionally unpublished.

Seems to me they're charging for value-add services. From the page you linked:

"Building your app is entirely free until you publish it. You do not need to choose your pricing plan until you get ready to publish your app."

And that seems only to apply if you publish through them.
