I'm on the same page as you. That was embarrassing. If he didn't want to answer boring questions then it would have been better for just Deepak and JB to have done the CC and Elon could have done a 1 on 1 special interview with Galieo and everyone could have been happy.
It was embarrassing, and I'm still not sure how I feel about it. But I have a hard time getting too worked up. They were getting questions that Tesla and Musk have said time and time again they weren't going to answer dating back numerous conference calls. These analysts continue to ask them, wasting everyone's time (and time on these calls is painfully limited). I'm not surprised Musk finally decided to nuke the call from orbit, especially given that he had a convenient out this time around in the HyperChange guy.
Elon pissed off a lot of big names today, but that's kind of his MO. This is not the first time he's said that if you're in it for the short term and you aren't a fan of volatility, GTFO.
Frankly I'd be happy if future calls were largely journalists and retail investors. We'd certainly get far more interesting questions...
Now back to incessantly refreshing my account hoping for a VIN...
