They state that the problem (if it is indeed a problem) is caused by hardware, but fail to say why.
Could it be that presenting it as a hardware glitch is a little more sensationalist?
1/. Apple will present a 'software fix' that will do nothing, but will lead the six people who believe they've seen the problem to proclaim that all is well.
2/. Folk will lose interest and go on to something else (as they did with PurpleFlareGate).
