This is more of a "be aware of your footprint" and less of a "security concern". This post is pressing hard on the fear of data getting stolen, however none of these things are major ways in which your data gets stolen.

It's phishing, social engineering, default configurations, weak passwords, no MFA, compromised online-services and supply-chain-attacks, and then, and only then are we even talking about actual CVEs in your local system and app environment. And usually we are talking old ones; for apps which you haven't updates in a while, as they are the most common.

What I'm saying is for your target audience, this is exactly the wrong thing to focus on. Tech savvy users might wanna look into this but they are very likely aware of all these things, and amateurs definitely should focus on basic security practices.
