What experience do you "cranky elders" have that makes this seem dangerous? What possible malicious intent can be applied to the knowledge that someone shares rent with their roommate, or the occasional bar tab settlement? There aren't even dollar amounts attached, and usually just cryptic emoji messages. Just saying "Information is power" makes it sound like there's been no thought put into the objection at all, I've not seen a single concrete explanation as to how this level of data collection is or could be dangerous. It seems like cowardly hiding behind a blanket principle because of paranoia about anything that can possibly be related to "privacy". >I'm very painfully aware that other people often feel amazingly entitled to have some say in how I spend my life. I have spent a lot of decades arranging a life in which, no, not too many people have any say whatsoever. I have absolutely no clue how this has anything to do with Venmo whatsoever.
