Study: P2P effect on legal music sales “not statistically distinguishable from zero”

Little of my day is spent watching TV or even reading online now because of the obscene amounts of time I spend without an internet connection. But when I do manage a few minutes of spare time and a WIFI connection, my Google homepage is customized with all kinds of RSS feeds. When I got to my homepage, this JUMPED out at me from Slashdot. Having watched the RIAA cry for many years now and try and convict everyone from an 80 y/o grandfather to a 9 y/o girl, I wonder what their motivation truly is. What is the possibility that this could finally open the RIAA’s beady little eyes (with green dollar signs) to the fact that the reason their cd’s aren’t selling/shipping is cause they put out crap?
