We can't all be network administrators

It's bad enough trying to keep your computer updated and secured. Can you imagine doing the same thing for your TV, refrigerator, toaster, kettle, light bulbs, vacuum cleaner, and personal assistant? Most people just want to be able to plug a thing in and have it work, they don't want to have to manage their home network in order to use those devices safely and most probably don't have the know-how to do it anyway.

When authorities warn the public of the need to do something the public is ill-equipped to do, they might as well be talking to a wall. The suggestion is not going to result in better outcomes.
