I guess most people using it have no idea it's a picture from Playboy, nor a nude picture, nor a controversial picture. I used it a lot myself when I was working on content based image retrieval simply because all the literature was using it. It never even occurred to me I was being controversial or sexist.
Now that I'm aware of the picture's history, I agree that it was a poor choice back then but I disagree that using it today is somehow an endorsement of sexism. Using it today only means you are using the standard image processing image.
Not the person you’re replying to, and fuck me if I’m wading into the question of sexism, but professionalism and maturity are things. We get paid the big bucks now, we’re not snotty kids in our parent’s garage; a whole world of acceptable professional behavior goes along with that.
