There seems to be very solid reasoning that its because they have "relief contracts" with "preferred vendors" and they can't have normal people in helping. There's nothing to loot in these areas anyway. I'm sure the "stop the looters" and "we don't want to have to save more people" line is the excuse they use. Sitting right next to the "for the children" and "stop terrorism" wrapping paper.
Yes and they say X/Twitter and social media is not tamping down unhelpful conspiracies that are hindering relief efforts. Prebunking, debunking, programming.
