Hmmmm... Hadn't heard about this. Interesting news. It is good that at the moment they will operate independently, but I figure at some point Walmart may be injecting all the Vizio TVs with their special kind of sales tactics, similar to how Amazon works with FireTV.
It's kind of the nature of the beast at this point I suppose. Wish more manufacturers would stick with Roku OS. But, it's all just getting more and more bloated for consumers.
