In the analogy, there is no such thing as a house kitten. They are all cute and cuddly lion cubs. Society needs to develop a deep awareness of this, in spite of the ocean of fraudulent advertising to the contrary. (individual-liberty-protecting regulation like the GDPR would be nice too, alas)

You have latched on to an important idea here.

Since most appliances now contain a general-purpose computer, it would be unfair to say that a device is incapable of hacking or hosting malware, because any device with the given sensors and radios and capabilities can be essentially reprogrammed at any time.

So, if we're looking at smart TVs with cameras and microphones and Wi-Fi and Bluetooth and all the connectors, or if we're simply looking at a an ordinary network device, they all fall under the umbrella of general purpose computer, and there is no way to trust their maker, or some equally capable programmer, not to turn them malevolent in some future update.

I don't view this as an issue of terms of service or of software or of your manufacturer. I view this as an existential and fundamental problem with dropping general purpose computers into your home and behind your DMZ.

Consumer operating systems like Windows and Apple have all kinds of countermeasures against this malicious use. But without the proper introspection and without the proper safeguards, a device that looks special purpose but is in fact general purpose is far more dangerous.

Getting technical - the way I see it, the problem arises from a combination of three things - sensors/access, Internet access, and source of software/authority.

Sensors/access is unavoidable, otherwise the device doesn't actually do anything useful. The point is it sets the scope for what the device is able to affect. When people say "set up a separate IoT VLAN" (that still has Internet access) this is basically what they're addressing - how a device can access other devices they may care about more.

Internet access is the catalyst that's created this whole dumpster fire - I don't care about the proprietary software on my keyboard/mouse/UPS/monitor/GPU/etc to nearly the same extent. I've got some TP-Link plugs that I control local network only. They don't get Internet access, so no updates, telemetry backhaul, etc.

The authority to update/configure/change that software is the crux. With proprietary software, there are no cuddly kittens period. Here we've got a case of a "legitimate" company choosing to be a bona fide attacker to increase their bottom line! The harm was exacerbated by a bug causing it to run amok, but even without the bug they are deliberately violating trust.

But even libre software can fall to security holes as well. Meaning you want to centralize the attack surface as much as possible, for administration's sake of keeping updated. "Internet" of things is basically the direct opposite of this - postulating many illegible fine-grained links between devices on different networks. Whereas really need more like the Home Assistant model, where peripheral devices may communicate over the network, but it's only ever over the local network. Think how ethernet is set up when used in industrial control networks (or at least how it should be set up, hehe).

Instead of a deep awareness, wouldn't it be easier to simply ban selling lions?

I think the two go hand in hand, unfortunately.
