I'm not on inferno yet so I can't say for sure, but the difficulty that Acts 2-4 provided didn't seem like fun at all. Maybe for sadists like HGR, but getting one-shot by random mobs doesn't strike me as particularly enjoyable.
I mean, when you get down to it, people are going to complain either way - it's too hard or it's too easy. I'd wager the too hard crowd outweighed the too easy crowd by a good margin. For those people, increasing the drops in Act 1 doesn't help because they don't really want to spend the time grinding for hours to get moderately better gear that might not even help.
