SpaceX has actually given the public much more information, and much faster, than other launchers. For one thing, this is a
development process, not the scientific missions that NASA typically showcases. And, we get to see in-flight video of both the booster and the Ship, including flap burn-throughs, etc. NASA does not even have the Starlink capability to do that unless SpaceX provides it for them. And, we see real-time graphics of propellant levels, altitude, velocity, vehicle attitudes, etc.
Complaining that we don't get real-time
explanations of every potential hold issue is ridiculous. And, if you were listening to the engineering and launch crews radio coms, you would probably not understand nearly all of the jargon and equipment references, anyway. There will probably be some explanation of the actual cause for the scrub, later. You don't have any reason to get involved in anything else.
As for the blast radius of an on-pad explosion of a fully fueled Super Heavy + StarShip, see the discussion at
https://www.quora.com/How-big-would...ueled-StarShip-Super-Heavy-exploded-on-launch . I am not going to get involved in doing those calcs, myself, because I expect that the FAA has already done that, and probably NASA and the Air/Space force for the Florida launch sites.
