I went back and looked, and the FAQ mentions that if you cancel your account, and return the device, you'll give a pro-rated amount. You have to click the link about canceling your account to see it:

We'll give you a pro-rated refund on your subscription once the device is sent back.

That statement could be taken to imply a prepaid amount for a service could be refunded if the customer was willing to part with something of value - the drive. What it doesn't imply is that the device is leased. If anything, it seems like a simple incentive to get a canceling customer to return the drive - if they don't, you don't give them their money back.

I think you are continuing to make rationalizations about this whole thing. The indication is the slew of blaming statements in your response above to emil. See "launching a public attack like this on a holiday" for reference of said blaming statement. I think emil deserves to be heard here.

Simply acknowledging that the device was intended to be leased and clarifying that on the KickStarter page should do the trick.
