This is highly reminiscent of "The Great F12/13 Engine Debacle of Summer 2012."
Just goes to show how little we enthusiasts matter in the grand scheme of BMW customers. While we all track these upgrades and changes for the slightest variation and become highly offended by these changes, we are the 1%... or maybe 5% to 10%, but that's not as pithy
The prime 6er demographic is older, a lot more female than these forums would suggest, and includes customers who often care most about the badge and the looks (i.e. clueless to changes like power output, hardware changes, and processing speeds).
Sad but I think it is the best explanation for BMW's, "sorry, but sh!t happens" attitude toward our complaints about these unfortunate decisions.
