What is the scandal on the part of Pope Francis? He hasn't changed any church teaching on ɧoɱosɛҳųαƖity or marriage. When he was in Argentina he was athorn in Kirchner's side as she passed the immoral legislation. Do you seriously think that he sent in an application asking to be elected their person of the year?
To start with, the pope should condemn the magazine and it's staff, it's readers, printers, ink suppliers, stores that sell the evil thing etc. in the strongest possible language that a pope can use to remove any possible shred of doubt about where the Church stands on the whole homo issue - this is his golden opportunity to condemn them for the whole world to see.
Remember the axiom
"Qui tacet consentit" (silence implies consent) - if, as expected, he does nothing, the presumption is that he has no problem with it - this is a (nother) grave scandal on the part of the pope.
