Would that logic also apply to subscriptions like Full Self Driving and supercharging? I think that even if Tesla can't disable the car over a terms of use issue, they could cancel full self driving and maybe ban you from supercharging.
If the self driving is fully paid for then no, they should not be able to disable it.
For denying the monthly subscription and supercharging, a case could be made that these were the features that influenced the decision of the purchase, and denying them has now made the purchase less valuable. A civil suit could be filed, but not sure how the courts would rule.
