All this talk of following your posek and Rabbi shopping make good points and is an interesting topic, but it doesn’t have much to do with the original question in the thread. The question was why do people still eat chalav stam?
I think that question was answered. Better tasting products most of the time, cheaper cost, and milk that lasts much longer without spoiling. (Perdue chicken may be better tasting, cheaper, and last longer than kosher chicken, but that too doesn’t have much to do with the original question in the thread.)
Mods, I think this thread can be closed now.
