I mostly see reflections of it in reporting by Clownfish and Eric July. The Joker 'male pregnancy' story that made it into the back of a 'regular' book speaks to what's going on.

I think it's mostly the unhealthy industry stuff: no sales numbers, slowdown of payments to comic book artists (which included DC and Marvel, but Disney being in better financial health than WB insulates the other member of the 'big two') and I recall (perhaps erroneous) speculation about DC shutting down its in-house comic production in favor of licensing the characters to third parties. WB being in financial straights really puts the vice on loss-leaders like DC comics.
