Megatron makes a fairly healthy profit, as do Samsung, 3M, Alps, Foxlink, Hon Hai Precision...amongst many others. The latter (Hon Hai) better known as Foxconn was at the centre of the previous scandal due to working conditions, the high rate of suicides etc. Naturally that time as well Apple was blamed for it, interestingly based on a 'journalistic' interpretation of Apple's own report stating that it wasn't good enough and working on a plan to improve conditions...
There is nothing new here, it is a (un?)healthy dose of human nature, eastern working practises, western guilt, and a bunch of journalists using big well known names for their own commercial gain. Oh and general public lapping up every word they say and getting their pitchforks out.
@gramps did you ever get anything manufactured in China?
