Kodi, (formerly XBMC) on the other hand, has a ton of legal add-ons (YouTube, Crackle, Dailymotion, Crunchyroll...) that enable it to be used for perfectly legitimate streaming.
So let me ask you a direct question. If the illegal add-ons were not available for this magic box, would people still buy it? I suspect the answer is no. Although the gadget is natively benign, it's main reason for being a hot item is illegitimate, based on the people who buy it, and their plans for how they intend to use it.
