You talk as if this is a recent thing that the Raspberry Pi has enabled. Yet people have been pirating software long before bit-torrent was around; and people have been using torrents, specifically, long before the Raspberry Pi's were a thing. I very much doubt the Raspberry Pi has made any significant impact on the numbers of people who torrent - let alone pirate in the wider scope of distribution mechanisms.
How would the Raspberry Pi have any relation to torrenting at all?
I think, business of software as a downloadable application is dead. See what Microsoft is doing.
