In my opinion, you really mean PR (Public Relations), i.e., Intent Sciences, if the contract is still in place, and, even then, they would need information from management to communicate. On the other hand, IR is quite limited legally in what he can communicate. IR, in my opinion, is still very lax by not answering emails for long periods of time, with, at least "There is no additional information to communicate at this time." or the like.
