The app just tried to tackle the general equilibrium where men send many requests and receive few responses and women receive many requests but are interested in fewer of them. As other commenters have pointed out, the equilibrium reasserted itself with women on the app just using a generic "hi" as the response. The word progressive has become more or less meaningless but in this case the hypothetical app your described earlier is essentially almost every dating app in actual day-to-day practice. Essentially the status quo is already completely imbalanced, they are just putting a twist on it that serves as the app's hook.
