Last time I checked, Walmart doesn’t sell conspiracy theories, stoke political violence, or demonstrably false, targeted advertising. You can muddy things with as many analogies as you like, but it’s quite obvious that Facebook’s engineering staff is closer to my example than yours.
Sorry, I don't mean this to be dismissive, but I don't think I can productively engage with the idea that Facebook is more closely analogous to the Nazi Party than to Walmart. I just wouldn't know where to begin.
