The only money EA had out for me for SimCity4 is about 拢10 in the late 2000s.
Since SimCity2013 they've seemingly given up on the franchise and all the DLC is made by users and hosted at places away from EA like Simtropolis.
My only concern about this new deal is if they come after us for some contrived licensing breach, but there's no money in it so why bother?
