the TL;DR is that Zuckerberg seems to want to move the company from being a completely open public space to more of a collection of private communities, because that is what, according to him, people are gravitating towards.

I don't think there's an explicit mention in there that they want to be a wechat like system. But there's also been talk about facebook introducing their own crypto-ish currency, so I guess it's not an outlandish idea either.
