Worse for them - though they'll continue to have some new sales, the initial spike is over, and the costs of maintaining their online infrastructure will continue to eat into any sales revenue for as long as they keep it active.
Makes you wonder how big a margin there is between sales revenue and ongoing costs.
Compared to Sim city 3k/4k, that is less than half the sale numbers in a growing industry. I would also guess that Sim city 2013 had a much higher production cost, server costs, administration cost and support costs.
And most wonderful thing, they can't blame pirates.
