Since every single other comment here is inevitably going to be some kind of applause and praise, let me briefly offer the perspective of some who have been silenced on HN and in the general tech world.
We know that homosexuality is a destructive force in society. While we love Tim Cook as a fellow human being and wish the best for him, this news deeply saddens us. It's yet another small victory for the evil one, and it will create a very deep distortion in the minds of so many impressionable young people who will now have a very wrong idea of what "normal" sexuality is.
I'm aware this comment will be down-voted to [dead] status very quickly, since tech culture silences any dissent or deviance from their own progressive thinking. But it's my duty to speak the truth even when it's uncomfortable or inconvenient. At the end of my life, at least I'll be able to say that I acted with integrity.
