You've just described how this scenario most likely will play out with othe appliances if producers decide to go the rental way. People may stay with their old ones... until they break, then it's time to buy a new one, but there's no non-"smart" appliance on the market anymore.
Exactly. To give a related example...look at Windows 10. I want to buy a new computer and will be in the market very soon. But I'm desperately clinging to my Windows 7 OS, and worried I won't be able to find something that ISN'T Windows 10. In fact, I have newfound urgency around this because I'll bet very soon I won't be able to find any Windows 8 computers on the market.
Its pretty easy to find computers that aren't Windows 10 (e.g., OS X machines are readily available, as are Chromebooks, and there are even sold-with-Linux computers); its harder to find ones that are Windows-but-not-10, but that's a different thing.
