I find this puzzling and it might not be doing what I expect/like. Two different things are tied on each others back here. Stripping meta data from the photos that are contributed is one thing, publishing on the map is another. I'd rather see these as different choices, allowing retaining location tags, while having the option to publish at the same time or some time in the future. Unpublishing from the map and republishing should also be possible. This is possible in Ps1, so why should that be different in Ps2.
