Dumb question from someone who uses old cars without OTA, how can cars get OTA if you don't pay for any internet subscription? Can't you say I don't want to pay

Dumb question from someone who uses old cars without OTA, how can cars get OTA if you don't pay for any internet subscription? Can't you say I don't want to pay for any internet costs when buying the car? Also ensure you don't connect the car to wifi. Isn't that suffice?
