Here's the one that convinced my dad that connecting everything is bad:
Your smart fridge knows what's inside and knows you just added a 12 pack of soda and donuts to the shopping list. They sell that data to a bunch of companies, including your insurance company. They know you have diabetes.
Your insurance rates just went up for the fifth time this year because your insurance company knows what you're eating.
And it's a good thing you don't drink beer or your car insurance would have gone up 'due to increased risk factors.' too bad you wanted to buy a new car this year.
Not only can you not afford it now, the price went up because they know you want a car. I'm sure they would make a payment deal with you though.
And every company will know all about the deal, the beer, the donuts, and all it took was sending money to whatever company had the information, and they were more than happy to sell it.
The more we allow companies to freely operate like this without regulation and without proper punishment for breaking the rules, we will continue sliding toward the hellscape of Ferenginar. For the non trekkies, it's a hyper-capitalist species of profit-driven assholes.
Also how many are repeat callers.
"Hey Bert, Old Man Jenkins called in another Santa Clause, do you have eyes on a plane around the airport?"
"Sure do, Tina. Small single engine is making it's approach now."
"okay thanks. I'll give you another ring when he calls in for the 243rd time this year..."
Back when I was a teenager in church, some of the local cops would be talking shit about the "crazies" they would arrest, and apparently one guy would call in about UFOs every time the nearest air force base used the training airspace that was overhead. Multiple times a week, and I guess never listened that it wasn't aliens.
