I found it interesting how Rob Liefeld speculated in his latest podcast that the reason Marvel effectively sidelined Moira and deemphasised the exploration of her multiple previous lives was due to the similarities to the The First Fifteen Lives of Harry August novel (as detailed on Bleeding Cool) and fear of possible further action from author Claire North.
I don't know how accurate that might be but it would certainly recontextualize the cancellation of Moira X's planned ongoing book.
