Will once again re-up the concept of a “right to root access”, to prevent big corps from pulling this bs over and over again: https://medhir.com/blog/right-to-root-access
The seat heating was apparently shortening the life of the leather seats. Its cheaper to include heated seats in all cars, than it is to maintain 2 different sets of production. The subscription basically offsets the cost of needing to replace the seats more frequently when the heating is enabled.
Likewise, if you manually enabled the seat heaters, then complained that the seats were falling apart quickly, having given you a legal out to get that feature enabled in warranty, would not have to replace your seats for free.
Not to mention, they apparently already ditched the subscription over backlash.
