Ignore them and steal from them anyways. If they team up to only steal from you then when the game is over give them a red thumb for teaming and also so you don't have to play with someone who doesn't respect the setup again. After that move on, there is nothing else you can do, they're the one limiting themselves in the game if they are playing with that rule when its not enforced. It's not worth arguing with them in the chat.
I usually play Arena where it is enforced and when I play regular I'm always relieved to not have friendly robber and can block someone straight away. I do like Easy Start though, Friendly Robber just changes the whole strategy of the early game though.
