I'd rather they not go third-party period, but they kind of went second-party when they made Miitomo and started making Super Mario Run.

So Microsoft is now 2nd party for making games on PC too ? What about the few Sony mobile games on the market ?

PC is MS' platform.  They innovate with DirectX exactly to push gaming.  Their own PC games use that system.
(obviously there is competing APIs on PC, but MS is pushing their own there with their own products).
Sony in fact released alot of PC games, which is de facto on MS' turf.  
The arguments why releasing similar/identical games on a platform besides one's own console is a horrible idea
make just as little sense for these companies as for Nintendo.  MS releases PC/smartphone software on Apple.
Apple releases software on Windows/Android.  None of those companies even "failed" before doing so.
