yeah I feel like there is politispeak behind this one. the rocket performed well until it failed catastrophically 
With NASA it would be 'rocket exploded after launch' with elon musk you get some crazy shit. Whats with the people clapping when its spinning out of control too, bizarre! I just find it odd people are never that kind to NASA with... post launch analysis
Until I watched the video, even after trying to do 5 minutes of research, it was unclear to me if it exploded or not. Impressive PR
I don't have any real problem with rockets exploding, I know their complicated especially when you are trying to be cheap, but damn the initial presentation I got seemed like it was made by Elliot Carver (James Bond, Tomorrow Never Dies)! It seems that is cleared up now.
This kind of thing is the difference between NASA and the private sector providers like SpaceX though.
SpaceX embraces a Silicon Valley type mindset of "fail fast and often", whereas NASA would spend over 10 years designing, testing and simulating a new launch system with it launching perfectly first time (SLS).
Look at how much effort SpaceX spent on trying to get boosters to land. They didn't care if they failed, because as far as they were concerned, the rocket was trash anyway.
I think there's a time and a place for this mindset, perhaps in aerospace engineering it makes some people nervous, but it is a unique attitude. It's not tolerable if you have humans in danger, but it's tolerable when all it is, is some investors and billionaires cash.
