Nevadaref wroteUpon what are you basing the official’s authority to not administer the throw-in? Should the official be directing the four teammates to stand inbounds once the thrower is ready to receive the ball?

While I admit that officials shouldn't be "coaching" players, in my opinion, all of these are examples of "preventative officiating" and to not do so and make a call with no warning would be an example of a "gotcha" call, "Look at me. I know all the rules".
Yes, there are gray areas between "coaching" players and "preventative officiating" that should be debated, but these examples aren't gray areas.
Note to Raymond: Nobody waited for Larry Bird to get in the semicircle.
