I have worked in IT for 20+ years, and have been in cybersecurity and worked with information security for almost a decade. I don't like these things. At all. And I'm far from the only one. I'm careful with my cell phone, and what apps I install, and what I allow apps to do or know about me. I'm definitely careful about what I do when on a public WiFi network, and we're teaching our kids the same things. It's not being "afraid of technology", I assure you. So to paint with as broad of a brush as you did discredits you and whatever your position is completely.
Google doesn't give one whit about you or your privacy. YOU are the product with anything Google does. This will be no different. As mentioned by
@wdwmagic I sincerely hope that Disney does the smart thing (no pun intended) and gives an easy way to opt out of using or even having these powered on in your room.
It's funny - The more "smart" things that get foisted onto the public as being great for them, the dumber the populace tends to become, particularly around privacy.
