I feel like the point I’m trying to make is going over your head. We understand that the studio politics are stopping these characters from appearing on television shows.HBO's The Penguin is a slightly different issue. There is no rights issue (as WB/DC owns all of the rights to Batman).
However, WB/DC believe that Batman is only suitable for animation or the big screen (live-action film). Batman appearing in a live-action show would "cheapen Batman's brand".
In-universe, it’s a glaring pothole. Spider-Man would not ignore Mayor Kingpin running amok. Batman would not ignore Penguin orchestrating a Falcone Civil War
