Agreed 100%. You can tell Elon meant it when he said that they are some of his heros, and that he's truly hurt by them lambasting a mission that he felt would make them proud.

It goes to show you that even our heros don't know everything, and even if they let us down we have to follow our own path. Elon Musk is a hero of mine, and I'm sure to many others. Not to mention he was Robert Downey Jr's inspiration for Tony Stark.
