^Exactly Liefeld has a terrible reputation.
I wonder if all of these people leaving is going to make the DC people look at the way they do things?
No not really. The editorial interference has been there since around Infinite Crisis and its follow up. Editorial bickering and politics apparently was a hallmark of the company since Paul Levitz was President. If the public firing of Dwayne McDuffie from JLA after he spilled the beans about editorial interference didn't change editorial, Liefeld and a bunch of others complaining isn't going to change much especially since McDuffie was far more loved than Liefeld.
