Note that immediately after this become public, Apple put Wistron on probation refusing to award them any more work and requiring them to resolve the issues. Governments really need to do the heavy lifting though because apart from refusing to hand over money/work they are very limited in what they can do.
I respectfully disagree. The only heavy lifting that governments need is to hold Apple and their executives criminally responsible. Apple has shown ruthless effectiveness in tracking down leakers and prosecuting them. But making sure the workers who are making their parts and assembling their devices aren't slaves or being abused is a bridge too far for the richest company in the world? I don't believe it. It's Apple…
I think I remember one instance where underage workers were discovered and Apple forced the supplier to finance their higher education. In another they found a false wall had been installed in a factory to conceal hazardously stored chemicals and, again if memory serves, immediately terminated the supplier's contract.

According to HN search this is the only comment in over 600 that mentions this page. Beyond the marketing text, the PDFs at the bottom cover thousands of pages of supplier guidelines, government filings, lists of suppliers, audit results, etc.
Take with as large a grain of salt as you'd like, but at least it is a primary source on the topic. Apple naturally will be tightlipped during their investigation of these incidents, but I'm curious how they will be covered in their subsequent publications.
