I believe you miss the main issue: Most people don't know or don't want to do computer systems administration.

People don't need to know mechanics to drive a car, or architect to live in a house and Facebook, Google... are doing the same with computers. You don't need to know anything about how computers work in order to use them.

There is no FOVO when you can convince your friends or family members to use a different and better alternative. The problem is that there is no alternative.

There is no alternative. There is not some kind of box I can buy for 30 dollars, connect to my network and instantly being able to connect with my friends, family or workers with another box automatically and without work on my and their side like you can do with a physical telephone.

There are lots of tinkering boxes for geeks. But they are too complex.
