Nintendo having all their games available everywhere a better business than restricting them to a console?

I guess it really depends. If their hardware continues to sell poorly (even worse than the Wii U) then going third party may be the only option they have left, although the 3DS has done rather well, so that isn't a necessary option yet. With the Wii being a really big success, that made them a lot of money. So perhaps the profits made from hardware sold is more worthwhile than trying to branch out to every device possible.

There's way too many things to consider, most of which I don't know, to simply say "One option is better than the other"
