Newsarama probed McFarlane for a response on the whole Angela being apart of the Marvel U now (probably because Gaiman needed to recoup lawyer costs, just like the last time he worked there). I'm going to sum it up quite simply for you. He said it's Gaiman's character and that whatever he does with her is good for comics and that's good for everyone.
What? Were you expecting him to be like, "Oh fuck that shit, I'm going to create a sexier angel wearing less clothing and call her Becky or better yet just Angel." Nope, short and sweet. I'm sure he made piece with this shit long ago and probably wishes he had been better at business contracts in the beginning days of Spawn.
