How much can we credit Miyamoto for Nintendo's latest failures? Because he's not the designer or director of most of the games from the later years. In Star Fox Zero, for example, he acted as a producer, and "Producer" is such a general position. He may very well have little to do with the game itself.

But who was it that decided to incorporate motion controls into a Star Fox game? Sales numbers show that it's officially killed the franchise.

Sales numbers show that decision killed the franchise?  Not the lack of multiplayer, or lack of content?  I'm curious to see how sales numbers showed that.
