I've heard the same thing from him and his apparatchiks consistently - and in his written testimony to Congress: "My top priority has always been our social mission of connecting people, building community and bringing the world closer together."
The scary thing is - some kid in Silicon Valley has decided that he will wield his power in this way. Government is bad. Monolithic companies are good. Community is about getting behind your smartphone and liking a picture and posting a meme (hyperbole - but ultimately the vast majority of online interactions are such...)
It's always good to challenge the status quo - especially so if its about how the world works and how people interact. But the underlying capitalist values of Facebook denigrate any of those ideals.
