I am also puzzled by lack of communications between senior rabbonim. Do we need a sanhedrin for that or maybe a WhatsApp group? For an example, r G Kamenetsky reported that r Eliashev banned his book without talking directly: after some people told harav that r GK broke their agreement to pause selling the book temporarily. HaRav believed information and later replied to r Gk: I am Not a Navi
