HFoS, the why is because they just don't give a rat's patootie about the brisket. I would bet that most of them assume it is headed to burger no matter what. Anyhting that steps away from "the norm" is just a "don't care" item of work.
I asked one of the local butchers I go to regularly what happens to all of the points they take off the packer briskets. He said they grind them up. So, I asked him to save me a couple, I would buy them whole. When I went in, assuming they would be around the cost of the premium ground beef, he said $8.99 a pound. WTH?! He said that the manager felt that grinding it was easier, and that he didn't want to hassle with saving a few points. When I talked to the owner, I mentioned that I felt oit was cheaper to sell me the whole point, than grind it up and extra labor, he said that it was special handling. B.S.
I'm feeling bearish, and I'm packing a Wusthof Grand Brisket slicer from MABA
