It's a very significant part of combating climate change, without which there is no hope of achieving zero carbon, and no company has done more to make that happen than Tesla.

One can praise Tesla while still acknowledging that it should not be blinded trusted to always work in the public interest, and also while recognizing Tesla's contributions alone are not enough for human civilization to get to zero carbon.

Minimizing how significant Tesla's contribution has been relative to other carmakers', and in fact, the vast majority if not all other companies in general, is not an honest way of addressing these inadequancies and challenges you highlight, and suggests to me a motivation unrelated to environmentalism behind it.
