I think Ranchu is being funny and honest. Never liked Nikon glass myself. Prefer Zeiss/Leica or Pentax, Canon, Minolta... Of course people that are invested in Nikon will never admit that there are better options. Just human nature.
I wouldn't call it a big loss if Nikon went under. I pretty much expect two or three manufacturers to call it quits in the next few years. You can see it coming.
And Ranchu isn't a pompous Jackass for pointing out what the truth is....
It is not the camera in your hand dingleberry; it is the brain in your head.
