That's a very long term goal I suspect...
Depending on what the expansions bring; they themselves will impact the background simulation; changing the conditions of the game etc..
So I suspect that there will be a subtle hand on the tiller for a long time.
And perhaps at times a not so subtle hand on the tiller...if they see the game becoming toxic for a group of players. Any group of players, not just our/your chosen gang.
I think what they meant is "independent under surveillance". If they see sensible things coming out, they just won't intervene. If something weird coming up, first it might a bug or balancing issue (unfortunately you can't really balance such background sim before release), or just unexpected consequences (we humans are very suspectable to selective memory). Either way it will be very interesting and I can't wait to see FD trying out something during Beta (just how events work).
