Likely a quality issue.
Coffee producers have several quality tiers and how it’s processed is dictated by the quality. Highest quality will usually get a medium roast and be exported to other countries where it can be sold at a higher price. The roast will usually get darker as the quality declines so they can cook off bad flavors which may include chemicals, mold, bugs, feces, etc. The stuff at the end is really digging at the bottom of the barrel. It goes into stuff like k-cups, cheap coffee, instant, etc.
