I'm very skeptical of this. Attractiveness is sort of a constant across population, and sorts into several bucketed gradients, its not as if there are suddenly a ton more attractive women or unattractive men than there was before 2012 - there does however seem to be fewer situations where people can meet via traditional means however.
Now if you want to argue that non-conventionally beautiful women are not connecting with their counterparts on the male side, that might be a more interesting discussion - but one I dont think that can be proved out with data.
