Putting OSes which wont be supported in a few years and apps which are there just for advertising the current generation of TVs into a device which easily lasts 5-10 years in nothing but planned obsolescence.
I tell you: Utterly Stupid and Easily Compromised Things is just the beginning of a long line of horrible problems. This is a fitting way to describe any "smart TV" older than 2 years and it even applies to new ones: They are not smart as Android or Entertainment devices and they never really were: The hardware they put into TVs to make them "smart" is usually worse than a $30 android tv box off e-pray.
My main concern with this is not televisions. It's the cars and other things like that. I've noticed that new cars now come with all sort of "smart" technology which can not be easily replaced. Cars used to have this standard hole where you'd put your car stereo. This had the interesting side-effect of car stereos becoming a very popular thing to steal. That aside, it was a good thing: There was a time where you could just buy basically any stereo and put it in any car. THIS is what I want for the "smart televisions" and the "smart refrigerators" and cars and everything. If you car/tv/whatever is 3 years old and your "smart" thing is slow then just rip it out and put a new one in and done. Will they give us such a standard? No way, not unless the big corporations are forced to buy some bigger over-national corporation like the EU.
