Add to this "smart" washing machines, fridges, dishwashers, air conditioners, irons, stoves, etc. and of course cars and TVs, all happily phoning home the user's personal data with their always on internal module that nobody can disable or filter, since they don't make use anymore of the user's home network.

I expect in a few years even shoes will connect somewhere while being powered and recharged by walking. And of course free gait analysis through internal pressure sensors and accelerometers, apps for running or dancing (turn on a IoT device by doing a tip-tap, find your ideal dancing partner, etc) will be the way manufacturers will sell them to the masses, at the price of more and more personal data being surrendered.

I don't care much about what people do with their privacy, that's their business, but how can I enter someone's house, shop or car knowing that there will be no less than a half dozen devices listening to my voice or shooting a picture of me without asking?

Note that I absolutely love the good that 5G and further technologies can bring. It's just some of their uses that concern me.
