Why would you not trust Tesla? Are their interests not aligned with yours?

Usually companies are mainly interested on getting money from me...

Implementing logic in an ASIC which cannot be modified and implementing logic with an embedded processor where the software can be modified but this feature is disabled is the same thing. Both are intended to be black boxes that just do one thing and nothing else. Yet for some reason you expect to be able to modify the embedded processor.

Trying to save the planet would be one way.
