Case in point: TV shows. You can either click a single button and download the TV show from really fast servers, be notified of new episodes (and even auto-download) automatically...
or you can go to a shady torrent site with porn popups all over the place, install a torrent client (and set it up, which behind a NAT is non-trivial for most laymen), find a good torrent search engine, download your torrent, and curse your machine because public trackers are full of leechers who don't upload.
Yeah, I'd pay for the former too.
