For most people, even those who don't subscribe to the internet requiring service, there is no way to disable it. Especially when the radio device is inaccessible.
On a separate note, I recently got a CPAP machine. It comes with a copy of the terms and conditions that i had to sign and return to the doctor. Before you connect it, you must attach an external radio device.
Luckily, they botched the delivery and the device was 4 months late. Then when they finally sent it, it went to the wrong address. I called and said i never received it, before the neighbors brought my package. That's when i learned that the $1000 device i got was actually a subscription for $50 a month after the insurance contribution. I never plugged the radio device and the machine works just fine.
I paid $1000 for a fan with a tube, but at least I'm not paying for the subscription and never connected the spying component.
