Kodi, Plex, the late Boxee are all pioneers and the pillars of what streaming services have of user experience today. I remember when I first saw Boxee interface back at the piracy-wild-west era and thought how wonderful and easy it was to watch a movie with it. I even had transmission setup on a NAS (DNS-323) automatically downloading my preferred shows that appeared without much effort on my TV.
The truth is that I didn't pirate because I wanted to pay nothing for media, I did it because I wanted the streaming experience and ability to have movies available on demand, not some cumbersome physical media whose purpose was only to guarantee studios/record labels profit at the expense of my consumption experience. They didn't care about me so I didn't care about them, something that changed with the coming of Netflix, Spotify, Google Music and all others... Now I gladly pay what I consider a fair fee for their services and amazing hassle-free experience. These wouldn't have happened (as quickly at least) without the 2000's piracy world and the media platforms build around it...
