Lets take those one at a time. So Twitter he fired a bunch of people and it works better than ever with more innovation. He called a guy a pedo who may be one and was talking smack way before Elon was. Maybe he misattributed some failure to someone? Okay, who hasn't done that? You say he went easy on Tesla safety.. with the cars with the best safety ratings of any car that exists.. still not getting it. You are mad he wants to save civilization also, okay... and that is bad again why? Because he is actually doing it by popularizing electric cars that can run on sustainable energy, or by giving internet to those who don't have it and could never have had it before? And supposedly you say he doesn't value human life, according to who? Why do you care how many children another person has, He has the money to have 10000 children and treat them all better than most millionaire children. Your question of "How is that ethical?" How is it not? You gave literally no reasons that don't scream an emotional attachent to hating him.
I should have been clearer. Sorry about that. My point is you can ignore everything but not hiring the surrogate mother.
It's not justified as he has plenty of kids and it's unethical because the mother does not get to see the kid ever. Not saying it's illegal. If you don't see any problem in it, then I have nothing to say.
I was a huge hero worshipper of Elon until I learn d about the surrogacy. He is just like any other rich ass hole.
