I don’t consider myself an activist, but I realize how much I’ve benefited from the sacrifice of others. So if hearing that the CEO of Apple is gay can help someone struggling to come to terms with who he or she is, or bring comfort to anyone who feels alone, or inspire people to insist on their equality, then it’s worth the trade-off with my own privacy.

If you're worried about messaging, people will just move to something else. You know if you legislate against Facebook and Apple and Google and whatever else in the US, they'll just use something else. So are we really safer then? I would say no. I would say we're less safe, because now we've opened up all of the infrastructure for people to go wacko at.

Our business is not based on having information about you. You’re not our product. Our product are these, and this watch, and Macs and so forth. And so we run a very different company.

The worst thing in the world that can happen to you if you're an engineer that has given his life to something is for someone to rip it off and put their name to it.
