C'mon don't be so literal. Hermit as in isolated from a social interactive context. For instance, take this personal example: I like trail running. Nowadays, the ONLY way to find out when a cool race is happening is through Facebook. See, companies don't mind losing a few of us hermits that decide to stay off social networks and so they devote a great deal of its resources to communicate (and build brand) on these walled gardens. Heck! I even know new companies that don't even bother making a website anymore, the FB page is enough. Whatsapp is even worse since in my country it has become the de facto means of digital communication. I have friends, family, work and shared interest groups. Trust me, from personal experience, where I live. if you do not have FB or Whatsapp, you are out of the social interaction, a sort of hermit.
