Is it fair to call Facebook a single-purpose-at-best company? They are the top social networking company in the world. Within social media is encompassed global communication, local communities, news and information sharing, etc.

Sure, there are a ton of negative externalities of that such as fake news spam. But it also puts them in a unique position to tailor their site to encourage the behaviors and enforce the values they want. I think the focus on local communities is an important example. Obviously local communities can create groups now, but there is a lot that can be done to encourage those kinds of communities and groups and discover existing ones.
