Funny, though. The article made it sound like she's shown a pattern of willingness to walk away from books that were forced in directions she didn't appreciate.
Was I reading into that as well?
I don't think you were reading into it too much, because it seems that many writers in any medium are like that. For example, Karen Traviss, who wrote the "Republic Commando" novels as well as a few other books featuring Mandalorians, walked away from writing for the Star Wars books due to being told to alter her work as well as that her previous work was being retconned (there were also a few issues with payment, but the focus seemed to be on being told to take her work in a direction she wasn't happy with). She didn't own the characters, much like many comic writers, but she still wasn't willing to go against the flow of what she felt was her story to tell.
They aren't the first and won't be the last.
