I don't think so. I think it stemmed from Apple's desire to make their SoC fully in-house for their iPhones. They realized they were onto something, and took it to a whole new level by focusing on desktop-class performance.

This was probably further fueled by their soured relationship with Intel which was responsible for thermal issues on MBP's for years, poor performance increases across their entire Mac lineup, and poor cellular radio performance on some iPhone models -- forcing them to settle with Qualcomm and ditch Intel for mobile radios.
