(Vice) It wasn't long after the September 11 attacks that the vultures descended on our collective grief, exploiting tragedy to make a quick buck selling commemorative items like Bin Laden dartboards and Twin Towers rugs.

In January 2015, following the attacks on Charlie Hebdo magazine, Joachim Roncin's slogan "Je Suis Charlie" was reproduced on every item imaginable, including hoodies. Roncin said he was "horrified" at the attempts to commercialize his slogan. The French Institute of Industrial Property has since clarified that it has rejected all requests to trademark "Je Suis Charlie."
