I have heard from more than one Rav that some Charedi Rabbis do not know how to get a message out. Their message might be clear to a follower of that particular Rav, but means something else to everyone else.
Someone might ask a Rav a Shaliah and the Rav will answer with a Posuk assuming the questionaire understands the answer.
Someone might ask a Rav a Shaliah and he will answer with a Riddle that a follower would totally get, but a not follower would not get.
A Rav might give a statement in a letter written weeks after event.
This is how things were classically done. I dont think some gedolim understand this system doesnt always work
