I did count the hot months, which would make the breakeven basically the length of your lease (well, I think for the lease I just compared the 3 year subscription which is slightly discounted) – but yes, if you figure that the person will unsubscribe outside of the 3 coldest winter months it's like a 10 year breakeven IIRC. I don't know many BMW owners that keep their cars for 10 years. To their mild credit BMW is at least charging what amounts to a discount for the subscription for their typical buyer, as long as they stay on top of whether they're subscribed or not. I guess you could say it's annoying to have to subscribe and unsubscribe, and it would make a lot more sense if the subscription guaranteed that the hardware was repaired for free. Still, heated seats rarely break in modern cars from my experience.
