Except that the equivalent isn't Mazda disallowing you to change your OS, but it's Mazda vetting every single destination you're allowed to drive to, getting a cut of every fuel purchase, getting a cut of every Walmart purchase you do while grocery shopping and preventing you from driving into areas that Mazda corporate doesn't like.

(Also, ironically, Mazda's firmware is rather easy to hack :) )
