Nintendo did what many detractors always said they should do to make their systems more appealing. Now some of the same detractors are angry that Nintendo actually did it. It's going to be hilarious to watch, if and when Nintendo is going to make another few moves like this.

"Wahh, Nintendo should work with third parties!"
"Wahh, Nintendo got third party exclusives by working with third parties!"

It does come out rather neatly
