Not so different from any other editor really. Have you seen all the books Marvel keeps canceling lately? You can't even just call it sales anymore. The new Ultimate Universe was selling really really well and then they pulled the rug out from everyone by announcing they wouldn't continue it after Johnathan Hickman's two year plan. Lots of good shows get canceled too. Now more than ever with streaming. Corporate sucks. What can you say. It's sometimes not even do to poor performance. Maybe they just want to move some parts around or there's some dumb behind the scenes thing or there's a surprisingly human issue with the creators and corporate isn't going to bother putting it on hold while things are resolved.
