Well, I don't know anything about marketing and you might have a point, but the severity of impact of these two words is clearly very different, so it doesn't look like a good comparison to me. It would raise quite a few eyebrows and more if, for example, someone released a Linux distro named "Auschwitz OS", meanwhile, even in the software world, there are multiple products that incorporate the word prism in various ways[1][2][3][4][5][6][7][8][9]. I don't believe that an average user encountering the word "prism" immediately starts thinking about NSA surveillance program.
