I'm thinking very hard, yet still don't know what you're trying to say.
You want a consumer TV to be like a Microsoft laptop, is that the benchmark?
Did you read and comprehend the rest of my statement?
I'm trying one more time. I'm not arguing against you, maybe read this again in a few hours:
I believe you want to have full control over the device you own (like I do btw).
For this you need to acknowledge that right now it is not in the interest of any party to provide that, because it requires additional effort, carries additional risks and doesn't create an economical benefit.
You have to MAKE it the interest of ANY party in the chain (the manufacturer, the seller, the consumer, the lawmaker,...).
Being an angry consumer is not getting you there, asking people to "vote with your wallet" is not getting you there.
--> Why? Because you won't reach a critical-mass of consumers to move the needle for the manufacturer to notice and take action.
Creating noise on security issues and potential hacking won't get you there.
--> Why? Because IF it creates ANY reaction, the public reaction will be to hold device-manufacturers responsible, which (if it works!) will cause them to just spend more effort to lock down their products even more, secure the trust-chain in the OS and simply stop operation when it is broken at any point.
Trying a mix of topics by mangling everything together, to create as much noise as possible? It will not get you there.
--> Why? Because even if that noise is creating a critical-mass, if it's not based on a sober solid foundation with a clear demand, it is not actionable and will die down. Everyone knows that this will happen and affected parties will count on that.
So. What GETS you there is "artificially" making it the interest of the involved parties, STEERING the manufacturer into the desired direction.
How do you steer things if the sheer economics don't do it?
(I don't know your experience, so YMMV from here)
From my experience, the only sustainable way to achieve this is that you literally regulate it, by demanding a LEGAL requirement.
e.g. Pushing for regulation to provide the user full control over the product if he wants it, acknowledging that the process reduces the responsibilities of the manufacturer for that device.
You do that by finding as many reasons, as much evidence as possible that this is a solid direction: Security concerns, environmental concerns/waste elimination, "ensuring a free market",...

So how do I know that?
Because I LIVED through it already (with many other active people in the scene), trying to make bootloader-unlock and community OS a default thing on Android Smartphones.
We amplified the topic when the industry was still new and growing, created more noise than there actually was, riled up journalists to act like this is a crucial buying decision for the market, lobbied the whole industry, to a point that they actually made it a competitive feature.
Doing all that against a juggernaut of interests AGAINST it (in US e.g. Verizon, which never bulged, vendors with concerns about unjustified warranty-claims, journalists/users stating that this is weakening security, etc.)
And what happened? It all died down because we didn't use the momentum to get it into a regulation when there was the chance. Some fruit-company demonstrated over years time and again that this doesn't matter, then even turned it into a marketing-feature to NOT give full control to the user.
Meanwhile the momentum and interest in the market died down, and for the past years we started to lose bootloader-unlock again in many brands, without any notable impact on their sales.
So if we have to do it again, in a matured market (like TV is), how do we do it now?
Again, YMMV, but for me, having lived through that already, the only viable way is regulation.
Regulation which demands a solid trust-chain in control of the vendor, AND the possibility for the user to unlock it to take control over the device.
Anyway. Peace.
