Tampering with a device increases your liability compared to not tampering with it.
Don't install it in your home if you don't trust it. Don't buy things with terms and conditions where you dont own the device if you want to own the device. This is a different problem
I have things installed in my home that I don't own. Electric, gas and water meters. The common factor with all of those is that their liability also remains on their respective utility provider companies.
You do not get to retain ownership and transfer liability. It's that simple. If you insist that you own the device, then YOU are fully liable for it.
I agree liability should be part of the discussion. If we create a legal framework around the subject and clearly identify what's allowed or not allowed by independent researchers and what the ownership model actually is, then this part of the discussion becomes easier and more easily applied to past precedents
