I agree with you. Marvel has went overboard with replacing the main characters in the MU. Too much too soon and people will start leaving, which looks like what might be happening. They have to tone down the revisions and stop pushing the new IPs.
But what's losing thousands in print vs losing millions in television and movies? Joe Quesada has referred readers to Johnny Appleseeds. Print out a bunch of new diverse schlock and hope one of those ideas make it to the big screen. Lose a little in print, win large in the media. It's only the comic fans that suffer.
