Facebook isn't optimizing for the preservation of democratic norms or decrease of polarization; they're optimizing for eyeballs, time, and attention (which obviously translates to money).

To answer your question, they may not see it because they don't care, and if they do see it, they still don't care as that's not their KPI.
