This has NOTHING to do with Smart TVs, read my posts and visit that link to understand what Altice/Optimum has been doing to HTTP traffic and how this interacts with DirecTV's slideshow screensaver since it's also delivered over HTTP instead of HTTPS. Again, this is NOT a smart TV popup, it's Optimum doing thier HTTP injection. The screensaver is HTTP delivered embedded HTML content which Optimum is modifying and inserting code to overlay their ads/promo banner. Since the screensaver isn't something designed for user navigation, you can't access the button to close the popup. (Basically, with embedded HTML content you have to both specifically code the container to pass navigation commands to the web content, and code the web content to accept keyboard/arrow based navigation and selection instead of the traditional point and click, which is what Optimum's overlay expects) Sadly like Slice mentioned, until we get some concrete net neutrality polices that prevent ISPs from shaping and modifying traffic, there's nothing regulatory that Optimum is violating by doing this. The only hopes of getting it to stop is if DirecTV switches it to HTTPS delivery, Optimum tweaks it so it only happens with user-agents for desktop and mobile browsers and it won't screw up devices that use embedded HTML content like settop boxes, game consoles, bluray players, etc, the consumer reporters of the local NYC media (where Optimum has the majority of their systems) picks it up and the backlash forces them to stop, or if it pisses off some of the key powerful players I mentioned involved in data hosting and delivery networks and they file a lawsuit against Optimum for manipulating their data to insert ads without the consent of the websites they host. Those players could also force Optimum's hand by terminating all peering agreements until they cease the practice.
