What the hell? The M7 is a marketing label for some COTS silicon they licensed from some IP company somewhere (probably ARM/Broadcom or one of their associates).
It doesn't make unicorns shit rainbows or defy the laws of physics.
Your comment isn't only disrespectful, but also misses the point. It doesn't matter if the M7 is a custom design or bought off the shelf. As long as it needs less power than the application processor to sample the sensors at some frequency, it fulfills its purpose.
