Were there any official statements about the reasons for the change or what else do you base your conclusions on?
If not, could it be the developers wanted to reduce randomness in loot generation for other reasons than pleasing a vocal part of the player base?
I'm curious because you seem so sure that "the whiners did it" and I am not as long around in the D:OS community as you. Also, I didn't find anything about it searching for "scumming" or "loot" here in the forum save for your posts. So some directions to other sources would be welcome.
