>As long as it technically doesn't lose functionality that's advertised, there's no problem in terms of consumer protection laws.
Disagree. Starting a wifi network in my home I have no control over and can't disable was not part of the device feature set when I bought it, and I would not have bought it if it was.
The functionality that was lost was my ability to control the wifi my own devices make.
>Same as above: the terms didn't change and they aren't what it can do now; the terms are that this device might update functionality and that future change, if applied to your device, will be applied to your device under the current terms that allow it. If you don't like that, you don't have to use the device's software and you still have the right to hit the hardware you possess a hammer.
Disagree. The terms changed because the terms never contained an uncontrollable wifi network in my home. Terms of use that allow unending changes with no thought to consideration (in the legal sense) aren't contracts of any merit. Contracts that allow one side to unendingly damage the other side without consideration have no merit, no matter what anyone says.
If I hit it with a hammer I'm still out the money due to their changes to the device I purchased. I'm taking a loss due to changes in the terms that have no consideration and are different than the terms I agreed to.
>As for if you ethically should be entitled to a refund, well, how do you determine the point where someone is entitled to grievances?
There is no such thing as ethically being entitled to a refund. It's fantasy.
>That's probably a way to directly stream to the TV
The TV does it whether you're streaming or not. You can't disable it, there is no setting to turn it off. The TV is hardwired to the router and isn't streaming anything. Even if I was streaming to the TV, it would be on my own wifi network, on theirs. There's no reason for them to control a wifi network in my house, period.
"Smart" devices are just devices that act against your interest interest because 'the terms of service you agreed to when you set it up had unlimited changes for one party'.
