Just a reader of this thread, but that wasn't my take on it. The text you quoted was, I think, an overgeneralisation (there are certainly manufacturers who perform above the baseline standards), but I don't think it was worded adversarially? It then provided some more information (some of which I have heard from others in the industry, especially around QA being pressured to pass defective items).

The post they are complaining about was a driveby dismissive statement that didn't add anything to the discussion whatsoever.
