Like most cable companies, Time-Warner Cable is devoted to evil and making as many people miserable as possible, so it makes perfect sense to me that they would steal Daenerys' dragons just to film this commercial. The Seven know they have no problems stealing from their customers.
FYI, your ability to watch Game of Thrones on portable devices has nothing to do with Time-Warner Cable, it only has to do with you 1) subscribing to any cable service and 2) also subscribing to HBO, which the only legal way HBO allows their shows to be viewed online. I seriously hope the reason little Drogon here is wandering the streets of New York is because he melted the TWC executives at the commercial shoot like he did at the House of the Undying.
