I assume this policy is to prevent accusations that Apple is using an idea from an unsolcited customer suggestion.
Still, the P.R. person could have seen this letter as an opportunity instead of a threat.
oops, I didn't read the article obviously, as it states the reason in black and white. sorry.
Back in the old days,
when my third analog board
fried inside my Mac,
I sent a letter
suggesting they make machines
that do not burn up.
They didn't send me
anything in reply . . . But
that's the business world . . .
