Sorry, but that's one of the single dumbest questions I've ever heard someone pose in these threads.
Why don't you go ask old school Sega fans, or even old school Atari fans, why THEY had a problem with their company of choice going third party? I don't know a single Sega fan that was originally "okay" with Sega pulling up their tent and packing it in as a first party console maker. So why the hell should Nintendo fans be "okay" with it?
Honestly, there are a lot of very good reasons I could care to name. But really, I'll just save myself the time by stating that if you don't already know why most Nintendo fans don't ever want to see Nintendo stop making their own systems, then you'll never understand.
Just know that IF that day ever came (I doubt it will), when Nintendo "goes third party", it will be a very dark and sad time in gaming history.
