a) Different in quantity? Do you have any evidence that the average freetard post torrents/internet has more content (that they would otherwise buy) pirated compared to pre torrents/internet. I would suspect not.
b) Better quality? Well yes, pirated stuff is better quality than it used to be, but so is paid stuff. Better technology is better I suppose, doesn't really make pirating any worse than it used to be. (and I would suggest the vast majority of pirated songs / movies etc are piss poor quality anyway)
c) Pish, Albums are dead anyway. Yes it is easier to get (pirated and to a lesser extent legal) movies and TV shows now (I don't have to wait for them to be shown on BBC/ITV anymore) but again this is better technology being better, not really making the modern 'home taping' any worse than it used to be.
But you are right Crossley's actions don't really have much effect on the morality of pirating content.
