The problem I see with these companies, where HW is the focus and not SW, is that their tech stack is a joke. I have no faith in their security models, or their ability to protect my privacy. These features always feel like they have been just added on with little thought of the surrounding environment. Anyone who has developed a Tizen, LG webOS, Visio app, will understand what I am mean. The platforms have significant variations between model years, and developers are flat out told that features will not be fixed on 2-3 year old TVs. This seems insane considering the level of trust they ask from their customer.
Buyer BEWARE!
