When they push a software update that makes the treadmill unusable without the subscription, now you're tied to not only paying for the service (at whatever price they decide that week), but you're also tied to the company itself continuing to exist and OFFER content.
A bunch of lawsuits have been filed, I'm sure it'll be reverted to 'the way it was' soon. (I honestly believe it was a largely clumsy move in trying to quickly tie a PIN code to the software to keep kids/unauthorized users from turning it on).
But it's a parallel here. My Google TV device might show ads on the TV network, but you pay for the device to not get ads on the home screen like the awful Fire Stick I have. (every time you hit 'play' to try to unpause a program, you are actually hitting 'play' on the terrible ad they gave you).
