The OP made a big deal about how it's different in China so we can't compare directly. My point is that this is a Chinese national who lives in China and has actually worked at the plant. Regardless of journalistic pedigree, the writer is vastly more capable of writing an honest story from the Chinese perspective than a Western journalist or the OP.

A NY Times reporter covering poor working conditions in a meat packing plant in the Midwest is also a story worth reading. It happens, sometimes it changes when it's exposed, but almost never changes without exposure. An American reporting on bad American working conditions is more impactful than a Chinese reporter reporting on poor American conditions and the reverse is also true.

Upton Sinclair was able to change things with his work on The Jungle. I don't see this as being a lot different.
