That has always been true. Remember "Comic Scene" Magazine? In the back of every issue they had a list of every comic book adaptation in any stage of development. Even if no movement was made for years. I was 11 when Batman was released in 1989. After its huge Box Office success almost every main DC hero was listed. Very few that ever were made, until recently. (I distinctly remember Aquaman and Justice League listed back than) I am not sure it's Warner Bros fault or really the online fandom that does not understand that. Shazam! Is finally getting made. The suit perfectly is appropriate for the character. But that is a big difference to Cyborg or Lobo which are basically names on a list until greenlighted.
