I think I may have the answer: free hosting of free software web apps, with donation/subscription buttons and some kind of libre storage option, e2e encrypted of course. Maybe with a JS implementation of Tahoe-LAFS? I should track down Zooko and see if I can get him to put down ZCash long enough to find someone to implement that.
I have looked at it. I assume you're thinking as an app distribution platform? It doesn't look like it'd necessarily be good for personal/private data from apps.
For hosting, I am thinking of something centralized and run by a nonprofit, since it should be as easy as possible to use both for developers and end users, and it should provide extra services like CI and CD in order to encourage people to use it and distribute their source as required.
