The Batwoman writers, J. H. Williams III and W. Haden have left the comic due to last minute editorial changes from DC Comics. And one of the main reasons has to do with Kate (Batwoman) marrying her partner.
Please part of their letter:
Dear Batwoman readers -
From the moment DC asked us to write Batwoman — a dream project for both of us — we were committed to the unofficial tagline “No Status Quo.” We felt that the series and characters should always be moving forward, to keep changing and evolving. In order to live up to our mantra and ensure that each arc took Batwoman in new directions, we carefully planned plotlines and story beats for at least the first five arcs well before we ever wrote a single issue. We’ve been executing on that plan ever since, making changes whenever we’ve come up with a better idea, but in general remaining consistent to our core vision.
Unfortunately, in recent months, DC has asked us to alter or completely discard many long-standing storylines in ways that we feel compromise the character and the series. We were told to ditch plans for Killer Croc’s origins; forced to drastically alter the original ending of our current arc, which would have defined Batwoman’s heroic future in bold new ways; and, most crushingly, prohibited from ever showing Kate and Maggie actually getting married. All of these editorial decisions came at the last minute, and always after a year or more of planning and plotting on our end.
We’ve always understood that, as much as we love the character, Batwoman ultimately belongs to DC. However, the eleventh-hour nature of these changes left us frustrated and angry — because they prevent us from telling the best stories we can. So, after a lot of soul-searching, we’ve decided to leave the book after Issue 26.
The writers also stated there was no anti-gay feelings from DC Comics, they just didn't like the idea. However, this doesn't look good for the comic company. They have lost a few folks lately. I hope they have a plan to address this because fans are about to lose it.
