What makes respecting aesthetic decisions a bigger conversation than the gameplay decisions of the developer? If I take advantage of an exploit (in a single player game) in a combat system or how a level was designed I don't really see that as disrespecting the developer. Using exploits in dark souls are often encouraged and crazy bugs in games like red dead or skyrim are sought out for the humour they provide. A large amount of speed runs are all about breaking the levels to reach the end the fastest. I don't really see a distinction in changing something like the aspect ratio. If it's not giving you the edge in a competitive multiplayer game I feel like it's fair game.
