This is my biggest worry about using this service. It looks great, but if they don't make any money, how can they keep it running for free in the long term? They should charge users money for storage, not give it away for free - hopefully they have a plan to do so soon but they should make that clear. It would also be nice to be able to completely self-host, that would be really reassuring, not sure if it is possible but they could certainly sell that as a service and support it for businesses interested in running their own keyserver and encrypted file store.
