Whether it is gender-associated or not, if negotiation skill isn't what your company is seeking in employees, it shouldn't be providing premium compensation for it (and,consequently, inferior compensation for people with the skills you do want that lack negotiation skills.)

Negotiation is not directly required skill, but refusing to negotiate will deprive them of candidates with other valuable skills, just because they would take better offer from elsewhere. It's not like negotiation is like performing some circus trick and getting paid for how well you performed it. It's finding a balance between what the company thinks you're worth and what you think you're worth and what you can get in the market. If Reddit says "we have predefined price and won't move" then either they would consistently overpay (which I have hard time believing in) or they would lose candidates that have better options. Usually such candidates are not the very worst ones.
