Cracking the riddle of Elon Musk was very difficult for me but, now that I have additional information about the man, I can put together a hypothesis. He does not strike me as a crusader or a man driven by righteousness (this was my major stumbling block). What I think, is the passing of his baby had lot's to do with what he's doing. He knows who is responsible for the death of his child and he wants payback. He wants to crush all of those vermin. It's personal with him. In other words, a cold vengeance is the force driving him.
