This is how every industry progresses as software replaces hardware. I don't think it's fair to blame Tesla for it. A modern car is much less accessible to the home tinkerer than a car from the 80s, because it's a chip controlling the fuel/air mixture and not a valve on a spring, and so on. As a side effect these machines are much cleaner and safer than before, so I'm willing to accept the tradeoff.
An EV is supposed to be much, much simpler than even a decades old ICE car. Aside from the tech inside the batteries, it should be pretty easy to tinker with.
