Preemptively ceding territory to regulators is not the right move. Rather the opposite. They should be preemptively bitch slapped and laughed out of every room they show up in, regardless of their intentions.
Of course, easy to say... But you can't even sue or blame them for their actions if you make all their moves by yourself first.
