Many evil tech companies exist in this world unfortunately and they want as much information on you as possible.
The main reason for this today is to sell your data to advertising companies but who knows what else they use your data for!
It could be possible for these companies to access your home surveillance system and watch you and your family at home. They would also know when you’re not at home.
Listen to your conversations, discover what your hobbies are, what TV programs you like to watch. The list goes on.
Of course we don’t think about any of this when we see an advertisement for shiny new expensive gadget.
