The title seems to be, sorry, click bait. Elon might have said something, but the article only lists the note from SpaceX - not Musk.
The FAA originally said the problem was environmental. Now the administrator says “safety”. What is it that is unsafe compared to the last flight? I’ve been following this for a couple months now and still haven’t learned that basic fact.
To get back to the point - Musk drives me crazy (even though I drive a Tesla and love it) but this has nothing much to do with him. SpaceX is largely run without him. Yes, he’s the primary investor, and has tremendous sway, but launch decisions are not part of that.
