It is not "so what" yet
I am afraid all those commenters banging on the point that this is not news, carry on nothing to see, etc, fail to realise that Apple is a global company and in some countries in the world you go to jail or you get sentenced to death for being gay. Besides, teenagers coming out to their parents usually do not get that "so what" reaction even in our first world countries.
So as long as these things still happen in the world, a celebrity coming out as gay is still news unfortunately.
Biting the hand that feeds IT
