I felt like a major point of the article was that it didn't consider being available on facebook/instagram/twitter as being present, since you're likely doing something else - you actually being with someone physically is very different from someone being able to look at an html page you curated and message you while your brain is occupied with work/life. You'd have no context around that person reaching out to you. You wouldn't know their mood for the last few days. In all likelihood, they wouldn't feel comfortable pinging a cousin far away in the first place.
