The retreat from difficulty in later Cataclysm wasn't because of forum complaints. It was because of quitting. GC in his quote there says players don't quit over specific game issues (like flying or loss of a particular spell), but he carefully said nothing about cumulative impact of many changes, particularly from design philosophy shifts.
BTW, they should be able to tell from in-game stats who your "friends" are: they are the other players you tend to group up with and exchange messages with. Extracting clusters like this should be straightforward from their server logs. They should be able to see that these clusters tend to leave the game together, or that someone is at increased risk of leaving if their cluster falls apart. This, not exit questions, may be the source of his observation about people quitting because their friends left.
