You can have IoT devices with LAN only. IoT doesn't mean that it needs to understand DNS and access WAN. For that you can have IoT gateways with proper security in place. The problem with "part of the device lifecycle" is planned obsolescence. I would be up for it though if manufacturers are forced to release the source code and all service information they have the same day they drop support/updates for a product. Edit: I don't think you realise how many applications of lot of "IoT" things have where they are only on a LAN with 0 internet access. Internet access should be optional, not mandatory.

IoT without Internet is just oT. I agree that not all embedded devices with networking capabilities necessarily access the internet, but I don't think you can call something that doesn't use have WAN access "IoT" just by definition. I think many devices without WAN access would fall under the "ICS" or even SCADA umbrella. Personally, I'd support a law that forces companies to expose their source code when they stop supporting IoT devices. Forcing companies to balance their trade secrets with customer updates should help the internet get more secure, even if it raises the prices at first.
