Easy enough to enforce. Put all your IoT devices into their own subnet/VLAN with no Internet access. Then, you’ll quickly see which devices you need to replace, or just not use as “smart” devices.
I have a ton of smart devices that don’t even connect to wifi at all. None of them have Internet access of any sort.
So it’s a skill issue, then? Got it. Any old PC + a $10 pcie network adapter can be turned into a router capable of it.
