I think the article’s implying that the 10% figure was for a huge chip, and the defect density is low enough that normal-sized chips get a much better yield. If you make a big enough chip even on a really mature process, you’ll get a terrible yield. Sometimes you might need a really big chip, though, and be willing to spend a ludicrous amount of money on it.
The article doesn’t state the size of the chip the 10% figure was for, though, and just lists examples of things that wouldn’t have happened if the figure for a typical chip was that abysmal.
