Considering that Zuckerberg is a great admire of China and apparently socialism[0], it doesn't come to me as a huge surprise that these "ethics" are guidelines for Facebook. “I’ve also bought copies of this book for my colleagues,” Zuckerberg was quoted as saying by a Chinese news website. “I want them to understand socialism with Chinese characteristics.” [0]: http://www.washingtonpost.com/blogs/worldviews/wp/2014/1…
I’m no fan of Zuckerberg or the CCP, but that’s ridiculous. Hosting a Chinese official at the Facebook office and telling a Chinese news site that he gave some copies of the Chinese president’s new book to his colleagues isn’t any kind of useful evidence about Zuckerberg’s personal political beliefs or Facebook’s governing principles.
The correlations between the ideology and what happens with Facebook is synonymous though, so it's neither far fetched. But I guess you need to have some historic understanding to see that (and that's a little too broad to present in a comment field).
(edit: for admin: I up-voted this post and got an "user mismatch" error as response page - perhaps something the devs want to look into).
