It is called Cover Our Assets.
What do you want them to say? But since this is not a problem to me and thousands of other people we don't have to follow that advice. But in case it does happen in the very, very, very rare case manufacturer is covered.
Also, I read in many manuals that manufacturer suggest to use only OEM lenses and accessories. And you know very well where this argument will end up.

Even though I did not mean to insult anyone and I don't know why you are taking it as insult can say that you are doing exactly the same thing. You are combating my and thousands people experience and actually insulting my and thousand people's intelligence.

Your insistence does not have any support either. Yet if there was a problem it would be reported somewhere but it is not so it is not a problem. It is only logical.

That is because in infinite Nikon wisdom they don't show it to you. In fact when you turn camera off some of the functions are still functioning, just take a look at the top LCD. My older NIKON D1 and D1x cameras turned completely off.
