This is not their fault really. Economics are out of their control. So are terms of usage of various cloud data providers. Not to mention, none of them have any native way of accessing the storage as a file system (at least on linux). Nothing is unlimited as bargain prices. Amazon's unlimited pricing was neer meant for this, much like cellphone unlimited internet is not meant as a replacement for broadband (at their prices). They'll eventually throttle or just terminate your contract.
