A newspaper doesn't monetize #1 (People come and hang out). Facebook is, first and foremost, a social media platform. People go there to learn about what other people they know are doing. So the cafe and Facebook have the most in common there. The cafe monetizes that hang out by selling you coffee and Facebook monetizes that by showing you ads.

Newspapers are very much secondary to both businesses. They enhance the experience but are not fundamental to it. They also both provide a service to those newspapers by providing a point of distribution. People might, as part of their experience in the cafe/Facebook, read the newspaper.
