I don't know enough to decide with certainty if the post in question is right, but it definitely seems earnest. I believe the poster sincerely holds those beliefs.
Of course the men choose to contribute but the incentive structure is for the women to foster a sense of intimacy or connection so they can exploit it for cash. It's a voluntary association, but it doesn't seem like a morally neutral or harmless association to me.
This is not to say that the harm men face from exploitation is greater than the harm that women face - or that women don't also face this phenomenon, but just that it is also a harmful byproduct of the service.
