I am also not sure how I feel about it, but one thing that immediately pops out to me is: You may cancel your subscription to this VPN service at any time by clicking the “Cancel Subscription” link in any email that we send you. If you choose to cancel, your access to the service will stop immediately, and Mozilla will refund you for any unused portion of the service period within your then-current billing cycle. This means Mozilla will prorate your refund based on the remaining full days of the subscription period. That's the quality and user centered experience I expect from Mozilla, I still remember trying to cancel my audible subscription, and I ended up having to google it because it was so obfiscated.
