FWIW, I will go out of my way to not inconvenience others. Sometimes, when I want to capture a very specific image (above water) that I expect will be crowded, I will arrive hours early to ensure that I can set up in the spot I want before anybody else gets there and I have to struggle to get a good location. The best example of this is sunrise at the Mesa Arch in Canyonlands NP just outside of Moab UT. As dawn approaches, dozens, perhaps close to 100 people suddenly arrive. Meanwhile, I have figured out where I want to set up, and have been there since 3:00 am. The result is that if the conditions are "just right", I wind up with a shot like this:

As for those other people that showed up "just in time", well, I will stay where I am till I have got the shot I want. I am not being thoughtless, I am planning ahead. If, I was the one getting there at the last moment, then it would be me who is dealing with a less than ideal spot and/or waiting till the crowd clears out a bit. The same thing applies when I am diving. If somebody is there first, I wait my turn.
