Well, that's one way to beat the paparazzi, I guess. Somewhat of
a Pyrrhic victory, but it's an empowering move amidst a powerless
situation. You'd do the same, wouldn't you? Why should someone else
profit from your photo? If you aren't gonna profit from it, then
some paparazzo sure as hell shouldn't either. In a way, this does
give her an intangible profit, that of self-empowerment. So good
for you, Sia.
