In this case, apparently there are not "somebody's" making up anything. Apparently, Apple had this many orders placed. Then, Apple cut that many orders down by 50%. It's not somebody guesses Apple is ordering X but Apple has just come in and actually ordered X/2. Apparently Apple is the player in both cases.
There are no incentives for the suppliers to report huge cuts in orders. They have owners and/or shareholders to answer to too. If anything, they'll want to puff up sales rumors unless they see that sales really are not there.
I realize that some of us feel some kind of obligation to spin this to the positive, so of course, we're going to try to imply it's all other players except Apple, but this is not fringe rumor speculation. Apparently X was ordered. Now it's X/2. The only player able to place such specific orders is the one wanting to buy the materials: Apple. It's not somebody like Samsung pretending to be Apple and ordering X only to have Apple to subsequently catch the villain and correct the order size.
Sure, there may be other possibilities going on here (if we want to play the defend game, how about: maybe Apple have brought on some other sources of these particular parts?). But this kind of info is somewhat far from my cousins, friends, barber was cutting the hair of a guy who knows a guy who dates a girl who's best friend works at Apple and the rumor is, unlikely as this sounds, that iPod socks have suddenly surged in sales again... and new colors are coming out on TUE.
And frankly: why do we find so much fault with the rumor machine, analysts, patents, competitors, even our fellow consumers when the rumor is negative about Apple but not when the rumors are positive? Why are they probably wrong only when the story sheds negative light toward Apple? If some of us believe what we are writing here, be sure to come back and punch the same holes in reliability of rumors when the news is very favorable about Apple. You never(?) see these same people doing that.
