Btw, from an application developers perspective it gets even better. 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. At all! When 2017 lineup comes in a month or so, all current Samsung SmartTVs will stop receiving app updates as well.
So your applications WILL stop working and start rotting after a year or so after you buy their TV.
