The technology interests me and I would gladly work on a system that implemented such features. As an ethical programmer, I'd be sure to incorporate security, anonymization, and be able to draw the line so that I can help businesses make more money (since that's what they pay me for), and advance technology at the same time. This is only unethical when it's used in a system that infers more information aside from general demographics (which, BTW nearly everywhere collects), and makes them vulnerable to interception outside of the pizza company.
