>Yes, people use Facebook. No, you don't have to.

I know several people who essentially need to maintain facebook and other social media presence to be employed because they work in social media adjacent fields or journalism, where social networks are nowadays the main source to do basic things like get into contact with sources and so on.

So no many people are actually dragged into these networks rather involuntarily. The same is also true when it comes to people's dating lives if one looks at the behaviour of particularly young people.
