I wonder about those social platforms too but for different reasons since I don't use them. Closest I get to social media are a few select forums and even then it has been debated if forums are considered "social media." That's a whole different topic anyway as they are not IOT devices.
Internet of Things is defined (at least one version of it) as "the interconnection via the Internet of computing devices embedded in everyday objects, enabling them to send and receive data." There are tens of thousands of articles a click away you can read that discuss the many security vulnerabilities of IOT devices. Our vehicles of today have become a large, rolling IOT, and as such the "connected vehicle" has its security vulnerabilities too.
I was being a smart aleck. I was making lite of what I often observe: "do as I say because I'm an expert - and here is my resume to prove it", followed immediately by action counter the position just espoused. An allegory akin to "the world is going to end in 12 years", excuse me I must leave on my private jet now. Don't take it personally, the Amazon employees listening to your Alexa might upset.
