The Oculus VR goggles (who has a TV anymore?) serving you Facebook ads also has attention sensors (hey it's already on your head, so it was easy to add that 5 cent brain-wave sensor!), and if your brain ever thinks "Hey, that looks interesting", they'd just tell the poor Deliveroo "contractor" to drop off the device at your house, for a "Free 7 day trial. Throw it in trash if you're not interested!".
