You were almost forced to use social media. Employers were at one point considering the requirement that you have Facebook, but then "russia" happened, and everyone began deleting FB.

You need an email. It is increasingly difficult to get email from a place that is not one of the big software companies. Google has decided to not be neutral on politics, modifying their search engine to prevent things from coming up. Why should we trust them with our email? They might decide that because we don't like the hate-of-the-month that we should be banned.
