actually if you read closely it doesn't say it's a manufacturing defect per se. Which makes sense given that we haven't seen hundreds of reports regardless of size, store v online etc. the better part of the problem machines were custom ordered, thus built to order and shipped individually from over seas.
the problem as the gentleman says is possibly caused by the secondary layer shifting and/or warping due to poor handling during shipping. The machines were likely fine when they left the factory. but Fed Ex or whomever was standing them on end, dumping stuff on top of the boxes, leaving them overnight or over weekends in the wrong temperatures or whatever.
this also fits with a handful of reports of having a new display assembly put in and no more problems

maybe because it isn't. the reports are all coming from tech/geek blogs where folks will always bitch and moan, often over and over on several sites, about something being even a tiny bit off. So problems always seem bigger than perhaps they are.
to call anything widespread you'd need numbers to back it up. Numbers as in how many machines sold, how many had a particular problem, how many were not fixed by a particular solution, the source of the machine (in a store or online, apple or 3rd party) and so on.
