On a positive note, you'll be able to buy different subscriptions, so it's not a complete loss for you. The medical subscription for the probe, which will notify you if it spots any polyps or rectal cancer. Or a "recreational" subscription, where you can engage the vibrating bit that's near to your prostate.
Oh the joy when you get a notification on your phone saying "what did we find in your rectum? Pay 50USD to find out" and it's a piece of corn.
