Had a feeling these things were a massive privacy intrusions, just didn't have any proof. Then you kind of weigh in on the benefits of having one in your home and for me... there's zero. What do people use these for? Weather? Ok, I can look at my phone, tv, web, etc... What else does it offer you can't get elsewhere.
But to have these constantly "listening" and using the excuse that it's for betterment of the service? No thank you.
I will never have an Alexa or her sisters in my home. I do not use Siri at all. I will not have an IoT device at all if I can help it. There is too much data that these devices gather that will be used against you. From the Fridge reporting to your doctor about that 2am cheesecake, to your smart TV calling the cops because you're playing a game and you shout (in excitement or frustration) "YOU F***ING WHORE I'M GOING TO RIP YOUR EYES OUT AND SKULLF*** YOU!!"
Then there's the Ex pumping your heater up to 99 degrees through the IoT thermostat in the wintertime while you're on vacation for a month. Or turning it off to let your pipes freeze.
I received a free Google Home Mini a couple years back with the purchase of a Nest. Hooked it up and two days later it started responding to voices on the TV. Clued me in that it's always listening and not just waiting for "Hey Google". Unplugged it right away and won't get any such device again.
