The cultural pushback is interesting, but largely irrelevant the same way the teachers objected to computer typed papers or using wikipedia as a citation entry -- a largely irrelevant footnote. It is used. It is used by kids. Adults may attempt to pretend to not use it and offer a socially acceptable reason for it ( come to think of it, this may explain some of my manager's recent comments -- he is very attuned to management hivemind ). Fascinating stuff really, because it suggests a lot of who we are is based on social proof.
