Probably 2 reasons:
Big Picture: Exxon-Mobil makes far more money off selling gas/diesel and doesn't care about the tiny loss of market share here.
Another reason is that BMW dealerships give free oil changes for the first few years of ownership, and older BMW owners may not care or notice that LL-01 is gone from the label if thats what they have been buying before.
As for the Pennzoil 0w40 dropping it, maybe they want you to buy the SOPUS oil at the dealerships instead.
