> ...a wooden stake through the heart of the word "consumer"
Same for the word "user", IMO. Very similar connotations to it: it's been too often used to mean someone incapable, lacking autonomy, needing a benefactor to make a decision for them. Which they do need, because we've been designing hostile and complex interfaces that strip them of said autonomy.
Compare that to the word "operator": evokes an image of someone operating a CNC machine, maybe piloting a helicopter...
