... And he's the one who's writing it.

The source of this allegation? J. Michael Straczynski himself.

In the current storyline, there's a lot that I don't agree with, and I
made this very clear to everybody within shouting distance at Marvel,
especially Joe. I'll be honest: there was a point where I made the
decision, and told Joe, that I was going to take my name off the last
two issues of the OMD arc. Eventually Joe talked me out of that
decision because at the end of the day, I don't want to sabotage Joe
or Marvel, and I have a lot of respect for both of those. As an
executive producer as well as a writer, I've sometimes had to insist
that my writers make changes that they did not want to make, often
loudly so. They were sure I was wrong. Mostly I was right.
Sometimes I was wrong. But whoever sits in the editor's chair, or the
executive producer's chair, wears the pointy hat of authority, and as
Dave Sim once noted, you can't argue with a pointy hat.

So at the end of the day, all one can do is try to do the best one can
with the notes one is given, and try to execute them in a professional
way...because who knows, the other guy may be right. The only thing I
*can* tell you, with absolute certainty, is that what Joe does with
Spidey and all the rest of the Marvel characters, he does out of a
genuine love of the character. He's not looking to sabotage anything,
he's not looking to piss off the fans, he genuinely believes in the
rightness of his views not out of a sense of "I'm the boss" but
because he loves these characters and the Marvel universe.

And right or wrong, you have to respect that.

In spite of unconscionably, impossibly dumbshit clusterfucks like "Sins Past" and "The Other," I never thought I'd see a Spider-Man storyline that had a broader, deeper, and more permanently damaging effect upon the character and his franchise than the "Clone Saga," but Jesus Christ, it's official: Joe Quesada has finally trumped the worst that Bob Harras had to offer.

I mean, when even the guy who created total crap characters like Ezekiel and Morlun, and was willing to write The O-Face Of Norman Osborn without complaint, is telling you that your idea is bad, you need to take notice ...
