I think it's progress. Tits aren't genitals, never have been and never will be. And there's a growing number of females in pop culture that are tired of it.

Zara Larsson posted a tit pic on Instagram a while ago, Tove Lo flashes at every concert, etc. Seems to be more of the Europeans doing it than the Americans, but that's probably because they enjoy taunting our puritanical nonsense.
