I like the part about "industry execs are thrilled with the arrangement". They get 88% and the poor artist gets 12% OF COURSE they are thrilled with this.
Things may have changed a bit since I last studied the facts about the music industry about 10 years ago, but I think you'll find that the songwriters (not the artists if the article is correct) getting 8.4% of the retail (whatever the actual retail is) is very good indeed. Unless they're really famous and can negotiate a better deals songwriters normally used to get 1-3%. OK, this may amount to pennies per year given iTunes Match usage/number of tunes matched, but it's better than nothing, which was the case before iTunes Match started.
Whilst there is much that was and is wrong with the music industry, we should at least acknowledge that the record companies (used to) do a lot of work to get artists recognised and sold. The fact that a well established and gargantuan industry is taking years to move into a different way of thinking should not be a surprise. Big companies are like oil tankers - not that nimble - whereas small labels and indie bands can, and do, react quickly.
