Well, it is simple.
Frontier Development clearly wanted to show that ALD had gone from being the champion of justice and fighter against all things corrupt (just look at how she does preparations and expansions) to becoming the corrupter herself. Suuuure, in the control systems the black markets are gone, but in the exploited systems, far far away from the vigilant eyes of the Just Mother Empress, the corrupt run wild and make a fortune.
Or some other bull like that.
