Should?? Like how things ought to be with the world? Facebook shouldn't even know who prefers organic food. There should be nothing tying that preference to any other aspect of people's lives. Facebook should be more like Reddit where people can have whatever accounts they want and can interact on organic food topics without identifying themselves or tying that preference to other interests. Or maybe Facebook should have an explicit opt-in for users to choose what they're okay with being used for ads… … should? everyone should use an adblocker and block Facebook's ads. Also, Facebook should offer a service where you can choose to portray yourself as whatever mix of qualities you want to set for each time you search for something. So anyone should be able to see what the algorithm delivers for a set of characteristics they can adjust at will…
Also, I should stop procrastinating on HN
I have to disagree with you on that. I'd put money on targeting a housing advertisement toward someone with a preference for organic food to be ruled discriminatory within five years. It's an unavoidable logical consequence of the logic driving today's complaint.
