I don't buy it. I'm sure Musk (and many others) would like nothing more than to watch the event live. Just having the stream doesn't mean they'd have to show it to anybody. It could be kept private. The fact that they don't have a stream at all means it must be pretty hard. Certainly it can be solved, but it's hard or expensive enough that other things take priority.

(Note that the seeming ease with which they send live video back from the rocket during the launch tells us nothing. It's relatively easy to receive high-bandwidth data from a rocket above the horizon to a tracking station with a big dish that it can point at the rocket.)
