Hats off to people like Carlos Guestrin & John Giannandrea, who seem to have pushed a cultural shift through Apple. I didn't think I'd see a site like this a few years ago, based on Apple's historic reputation of strongly discouraging employees from publishing research.
Not to take away from the people who worked hard to shift the culture (which is always hard at a large company), but I saw the same shift happen at Amazon and it came down to a simple fact - it's very hard to recruit and keep the best talent if you don't publish. You don't build ML reputation and the best researchers often don't want to work somewhere where they can't add papers to their resume.
I've turned down military contractor work despite it paying better than my current job.
Being able to contribute to society goes a long way.
