You're telling me, if I run a clinic or rehab facility where women with trauma are more comfortable with other female therapists, I'm somehow required to advertise to and interview both men and women for a job - even when I'm only short on demand for a female therapist from a specific demographic or with certain qualifications? The same would go for a shortage of male employees based on patient or clientele requests and demands.

I'm not saying Uber has a reason to do this. They may or may not, but to say this feature or ability is illegal is just idiotic. In fact, it's rather useful and worth paying for in my opinion.
