And besides why in Hell would I want a desktop CPU in my fridge or TV?
On a personal level I am with you. I do not care about CPU in the Fridge.
Let me guess, you are not an avid follower of Kim, Klohe, and the like too. But 10 Millions or more are.
In other word Reality, Personal preferences, and
wishful thinking are Not equal.
The main reason that CPU in appliances are Not spread is because they need to be Networked.
At the moment the only way to do so without the Users know anything about such functioning is to use Ethernet over Power line.
Unfortunately (or fortunately) Power line is not yet solid Technology to be safe to use on Tech. Ignorant consumers.
Be sure that within two to three years that this issue would be resolved the majority of the Fridges used in the USA would be new model with CPU.
I reside in NYC (sure one of the most advanced city in the world). The majority of the people have the latest iPhone, when you ask them which IOS version they use, they do not what you are asking about. Similarly the majority does not know if they use Win XP. Vista, Win 7. 8 or 10. They use whatever Win version came with their Dell, HP, etc. Desktop/Laptop.
Some of them have Win 10 Auto Upgrade Push on them and they are running in fear looking for help because they do not Understand what happened.and are afraid that there were Hacked.
If you go to the basement of Apt. Buildings in NYC this time of the year you will find numerous amount of fully functional 32" LCD/LED TV.
Why? Because the Holiday sales entice people to Upgrade to 50" or more and feel good about themselves for few hundred $$.
