Yes that did strike me as a bit of a curve-ball given the direction the article was slanting. Maybe the reader is left to conclude that if older people watched more porn - the economy, politics...would be better! Obviously not as that would be silly, and yet I would not be supprised if I read an article with that whole perspective as a follow-up.
Boomer had the Summer of Love, the Pill, abortion and working antibiotics for social diseases. Then after the decadent 70's they brought us HIV/AIDS. So in addition to everything else, boomers ruined casual sex. Millenials are left with porn. Granted there is lots of it - but its still just porn.
