DC's offerings for Comixology have some pretty poor choices among them

For their GN offerings on Comixology, DC has offered more New 52 items than anything else, and even Identity Crisis, Blackest Night and Flashpoint are some of the worst they could give anybody unfortunate enough to stumble over them on a digital platform. How come they don't seem to have classic stuff offered? That just shows how little they really care about their older products, even for online sites.
