I have seen quite a few articles like this one about different morally questionable behaviors.
step one: Millennial writer does morally questionable behavior and gets a justifiable backlash.
step two: unable to accept that he/she was wrong and should change this behavior, he/she looks for like minded millennial reference material to support her morally questionable behavior.
step three: Writes article suggesting the world should change to accommodate her behavior because she doesn't want to feel guilty.
Monogamy is a contract, if you don't want to be monogamous end your contract.
