Nope, sorry. If they're including a hardware device in the car I Just bought, I reserve the right to use it as I see fit. If they want to charge for it, that's fine, but they only get to do that at hardware-purchase time. This whole "oh well that's a SOFTWARE feature, that's different" mentality is toxic.
Subscriptions are fine for things that need ongoing effort. Onboard data connectivity, or map updates, controls that have to go through an outside server, or the like. Not "the privilege of sending power to a resistive heating loop that's already built into the seat cushion".
And no, I don't agree with Tesla selling partial software-locked battery capacity either. Install the full battery, I expect to be able to use the full battery (minus whatever part is known by all parties up front to be reserved for wear leveling). If they want to sell a partial sized battery, then install a smaller one - maybe I wanted the weight reduction of carrying around fewer cells for some reason.
