Pray tell, how is this causing a problem? One could reverse the gender of the pronouns in TFA and your argument still holds. In a perfect world, everyone would use "they." Some people consider it necessary to respond to the prevalent usage of gendered pronouns to reverse the gender in common usage for the purpose of inciting conversations exactly like this one. IMO it's working to bring gender assumptions from a subconscious to a conscious phenomenon, which is the biggest step toward dissolving the underlying assumptions.
