You don't need to use devices. Other people are, so you will be part of it. Any device in your proximity will listen to you, any photos other people take of you will identify you, public cameras or facitities will surveil you, smart energy meters will know what you do in your home...

That is why the position of "I don't care, because I don't use that tech." or "It is peoples choice." Is so useless... We need strong regulation... Worldwide.
