While I'm inclined to believe Musk went into these industries (at least initially) because of fairly altruistic desires, it's important to note that this is is a narrative that originates and is promoted by him. That is, it would be foolish to make decisions based on that being true and also reflective of his current motivation without very good current evidence to back it up.

Now, I have the luxury of being able to take him at face value because I have no vested interest in any of these companies, as you may not. That said, a fair many people here do in some way or another (as a customer, an investor, or in some related market or field). It behooves them to be very critical.
