...but also that you're finding out. What google search would you suggest to guide folks to articles about why seemingly innocuous data are not as benign as they seem?
I wouldn't. If you're really interested in why security, privacy, etc., matters - don't google anything. Googling things (or using any other search engine) is giving away your privacy. lol
Go ask a person why it matters. Go to the library (yes, they still exist!). Contact companies who specialize in security and privacy.
