You have to look at the entire last paragraph, two sentences, to get the context.
"Ultimately, the shoot was a bad experience for Moss, but a turning point for fashion and art. Back in 1990, she took one for the team."
And if it needs more explanation, it comes higher up:
"...our fashion director Katie Grand was at pains to emphasise that a fashion shoot was a collaboration between model, photographer, stylist and all the other people who worked on it..."
So the team is all those other people who put the product together; the claim is that it's not just someone pointing a camera at a woman. And what's done for the "team" isn't just the pictures made that day, but a change (maybe) in the fashion world forever after. Of course there are people who really do concern themselves very greatly with this fashion and modelling and "art" business, and this article is basically addressed to them. Whether it's just a load of guff that everyone else should dismiss, I don't know.
Kate Moss may have hated that first experience, but let's not just say it's "exploitation" when we know she has big piles of money to console her. Would she want to go back to age 16 and just be ordinary?
