Nintendo still uses motion controls; they just made them portable and more resilient with gyros instead of IR.

The attachment rate was likely lower because of that.
A lot of them were played with a Nunchuk to emulate a classic controller (or attached to the actual Classic Controller or Rock Band instruments to play cross platform games).
The motion control that comes to mind beyond Wii Sports were circling the Wiimote to collect things in Mario.
Even games that didn't require motion controls for basic gameplay still required you to do things like turn the controller around and use the pointer to select options from a menu rather than using the D pad. (I'm thinking Punch Out). I think Donkey Kong country occasionally made you shake the controller.
