If Apple’s key strength is its home-grown talent and corporate culture, why do so many of its big successes over the past 30 years come from companies/projects it acquired or absorbed? From OS to chipmaking to its iTunes ecosystem to pro apps to its compiler tech — it all came from outside the company. Maybe that is why we're seeing so many purely-Apple-made projects stumble lately. Maybe Apple's at its best when pouring resources into third-parties at scale, not nannying them out of existence?
