If they say "no", they're speaking for Amazon, and saying "we give you a right to infringe our patent". If they say "yes", they're speaking for Amazon, and making the firm look douchey.
Mu - unask the question.
That doesn't mean we should give the engineers who come to this time a hard time about not answering it. It's just a legitimate thing to ask out loud.
If you know the engineer can't answer it, it's silly at best to ask it. At worst, it's malicious. See http://rationalwiki.org/wiki/JAQing_off (If you don't know that, then there's no problem and a quick explanation why it's not worth asking should end the thread. It's not something I'd take someone to task for.)
What you are referring to is anti-intellectualism, to ask questions for the effect of the question itself. Hiding behind the hypothetical, and not for the desire to know the answer. The root question here wanted to know an answer, not play any game.
"Silly at best to ask it"? Again, what on earth are you talking about? If people have an insight to give, they will give it.
"Not something i"d take someone to task for"? Do usually tell people the things you don't feel like doing?
