I prefer to interpret it charitably: the line between influence and manipulation can be pretty fuzzy, and some people come to a conclusion of, basically, "don't do it at all because it's always selfish."
I think it's a flawed view because it's impossible to go through life not influencing anyone and not wanting anything from anyone, so you may as well try to do it in a way that is generally win-win or at least not win-lose.
