I think the issue is the sharp angle Apple used for the camera plateau. The anodization doesn’t adhere to that sharp corner well and therefore it scratches easily. This hasn’t been an issue on the regular phones because the camera bump is made of glass. And the aluminum band around the edge has smooth gentle curves that are easy to annodize.
So the pros seem to be more prone to scratching around the edges of the camera plateau. It’s pruely a cosmetic issue. Everything beyond that is the usual routine of people blowing an issue way out of proportion when a new iPhone launches.
