I never claimed to decrypt the source code or any of that good stuff. Also you are neglecting the fact that I have mentioned it happens when multiple people are in the same system, which as you said, means the server is updating all those clients with the same information thus meaning the NPC actions are no longer client side and are taking up the bandwith. Also it is a much different experience in freelancer when you are on/in the same structure as the server PC.
Anyways like I said earlier, it is just an idea to add a toggle (which means each server can make a choice on using it or not) and I'm sure it would be a relatively simple task to add.
As for your comments on my knowledge about the Source Code, I am purely stating what I know based on observations compared to netcode problems in other games and netcode problems in this game.
