TL;DR: Nintendo use a MIT licensed code.
What tends to be ignored is attribution, respect to Nintendo for having good internal processes in this regard. If there is any news here, it’s that.
A big chunk of WebKit is LGPL and Blink too as a consequence. They might be successful thanks to that too.
Honestly, I don't find your obvious so obvious.
But they did use the code. So MIT/BSD work?
