If the author was really done with social media they would delete their accounts. Since the accounts are not deleted the door is still open. I deleted my accounts over 5 years ago and don't miss anything. In fact I think it has strengthened my connections with friends pushing me to text and call more people. The only regret I have is as a security researcher I lose out on some good OSINT data. There are ways around it but the walled gardens are quite secure and require ID to enter.
