IMHO, the majority of consumers, who the music business is primarily aimed at, don't care. The compression can even be better when listening with headphones, from a cell phone, in a noisy environment.
We, consumers who really care about the problem are a minority, and the pressure against loudness war is minimal.
The uncompressed editions, Blu-ray editions, and some Hi-Res downloads are exclusively aimed at that minority... to keep us happy as a new variant of "bread and circuses".
Another explanation I think of is that the musical industry could be looking for new hipster consumer, selling "better quality" Hi-res editions that are really aimed to that people that listen from mobile headphones at the street or swiming pool, to whom loud music at a good volume sounds very good.
