I don't see how this is genius. Having hosts not know the contents they perform services for has been desired for a very long time. Research on homomorphic encryption predates mega by quite a while. And I am sure there must be backup services that already encrypted client-side long before mega. The only reason why there wasn't something exactly like mega earlier was because browsers didn't have the capability. And it seems mostly like revenge for having megaupload shutdown. The profits aren't very good when you can't de-duplicate files (because the content is encrypted) or do anything else clever with the data. You just become a dumb provider of hard drive space and bandwidth. Anyone can clone client-side encryption.
