I guess it depends on the team. Apple unlike Google hires for a specific team. Team that I was talking with would not allow open source contributions. This is true for most of Apple. I have a lot of friends working in Apple. They sent project Titan people to a battery conference with a fake company name which they actually registered and made people believe it's a real company. It has a Crunchbase profile and all that. They published zero papers from their battery research. That's the Apple you should know.
