When I used to actually read titles like NEW AVENGERS monthly, I would often rip into Bendis for, among other things, an arrogant aura that seems to penetrate into some of his work - especially when he is doing something "edgy" or "explaining" something. And I would often get counter arguments like, "you can't tell if a guy is arrogant or full of himself by reading his work", because writing is a totally emotionless affair in which none of a writer's personality or quirks or desires leak in. 
And then we get interview lines like this:
	
		
			
				Bendis said:

Now, I'm no humorless fop. I know very well that all comic writers are aware that regardless of reputation or whatnot, they will have "haters" of their work. Alan Moore has haters, for heaven's sakes. Many a writer has poked fun at the fans who rage at them for stories or whatnot. But a simple fact is that if a writer is changing something major about a character, this reaction is fairly expected. It isn't isolated to comics. Just try and change ANYTHING about a major character in STAR TREK or STAR WARS and you'll feel some "fire breathing fists". Heck, last year I made the mistake of blasting SCOTT PILGRIM without reading it - there are bones in alleys of people who have paid the price for that. So, I get it. 
Even still, Bendis seems like a guy who almost relishes the attention and "play" that one of his "big idea" runs gets. It seems obvious that the editors are giving him whatever he wants with MOON KNIGHT, and if he wanted to make Marc Specter a Kree cyborg, that would happen. 
And, for total disclosure, I am a big fan of Dan Slott and even he has lamented some of the things about Moon Knight that his fans have no problem with - the Khonshu connection. If Slott was the one writing MOON KNIGHT, would he be just as capable of doing major changes? Yes. Part of me thinks he cares too much about the continuity of Marvel to do as major a thing as Bendis is, but it is possible.
Still, this reminds me of what has happened to Daredevil, and I know I have made this rant before. DD has been trapped in a vicious cycle of one major story arc for the better part of the last 20-25 years - "his life is destroyed and he has to rebuild from scratch". This naturally happened because the Frank Miller run and FALL FROM GRACE are his iconic stories and writers and editors want to endlessly duplicate them. So the story has to be retold, but it has to be done in a more extreme way every time. So eventually, we get SHADOWLAND, in which DD is possessed by a demon, builds a ninja temple in Manhattan, talks like the Shredder, and has a death experience. 
I might add that the X-Men franchise, for decades of time, has been caught in similar loops of "imitate Chris Claremont stories" for so long that it is easier to find runs that don't.
Moon Knight's loop is sanity stories - every writer seems to want to play with Moon Knight's sanity, since he attains different personalities. At first these were all roles he played for various crime fighting purposes, and some were easier to slip into than others. Now, they are full blown multiple personalities, Two-Face style. Every writer has to tell their "Moon Knight is nuts" story, and it has to get more extreme every time. Huston had Marc carving moon shapes into faces, scalping enemies, and throwing crooks off rooftops. And now Bendis will make his multiple personalities more extreme. Hey, the hints were there in his USM run when he created his own version of Moon Knight - a version, with merely a few cosmetic differences, that we will see in his run with Maleev. 
The irony is that Marvel's yes-men editors don't do Bendis any favors, either. They keep him in a loop in which he not only repeats himself endlessly, but is praised for work that is not even published and criticized yet - who could maintain high quality when your bosses are endlessly rubbing your shoulders? Much in the way that many people need a good, brutally honest friend to remain better people, I think Bendis has needed a brutally honest editor for at least 6 years now. He doesn't have one and he still doesn't. The iron fist of Jim Shooter is such a trauma for Marvel Comics that I think a lot of editors instead want to be honey bears, like modern day parents who don't want to be "as strict" as their own parents were, and they thus spoil their kids rotten and turn them into shallow, selfish, low class thugs.
I am sure Bendis has some pressure to maintain sales draw. But that isn't the same as quality. McDonalds sells more burgers than any "high class" burger joint, but that doesn't mean their patties are better.
From a financial standpoint, MOON KNIGHT is a franchise Marvel wants to see selling better. They have been working to keep a title in print since 2006. Sticking their A-List, #1 writer on a relaunch with the artist he collaborated with for his career defining work makes good dollars and cents sense. I could argue that if Bendis can't make MOON KNIGHT sell, no one can right now. But the problem is that if he totally shatters the character, and even if it doesn't sell, it becomes "insta-canon" and every writer down the line HAS to follow it to the letter. 
The only writer who had the stones to say, "**** that noise" and did a 180 on something Bendis wrote was Peter Milligan. At the time he was writing X-Men, and barely 2 months after Bendis deliberately depowered Iceman in the final issue of HOUSE OF M, Milligan, who had Iceman on his roster, re-powered him effortlessly with a hand waving gesture ("I just willed my power back enough"). You'll notice he doesn't work as much with Marvel anymore than he did back then. I doubt they'd offer an exclusive contract. Maybe it is coincidence, but maybe it isn't. Maybe there is a price for crossing the Bendis mafia.
There's more to do with Moon Knight than endlessly making him crazier. A pity it may be a while before anyone tries.
