"I didn't make this one for the critics" frequently means "I made the movie I wanted" or "I made the movie the studio wanted". That statement could boil down to "I'm not concerned about money, I'm making a movie I wanted to make in service of the fans" or "I made a movie that I knew would make a ton of money, because people go to see this junk even if critics don't like it". CEO's don't have critics in the same sense that movies/art does. The financial/business sector work on completely different axes to judge performance. Elon seems to be more focused on his vision of the Big Picture (solving transportation problems, moving to new planets, fixing the energy crisis, etc) than making money in the short term (which might be over the next 10 years). He appears to be a man convinced he knows how to help fix global problems, and believes in his mission more than making money. You still need money to change the world, so he's also tried to do very well at the business side of it. I'm not convinced Musk will fix humanity. I'm also not convinced he won't. I just feel that this specific statement, that Tesla isn't a business everyone should be involved in, feels like a "we're mission driven, not money driven" proclamation to me.
