For example Samsung locks down the application store updates after one year for each SmartTV models. So right now, SmartTV app developers aren't allowed to update ANY applications for 2015 and olders models of Samsung TVs.
That doesn't seem to be true. My 3 yo Samsung TV is still getting app updates and my 5 yo Blueray player (with the same software) is also still getting app updates.
Agreed, my 2015 Samsung TV just got a flurry of new app updates before Xmas, including Amazon Video and Spotify that previously weren't available at all.
