Nice try, but Facebook failing in China is due to it not being accessible from there. Why would Chinese language have anything to do with it ? Maybe it would fail anyway, but for the moment it did not even have the possibility to try.
I live in China and I can assure you that the censorship is not invented by reporters. Facebook, Twitter, Youtube, Blogspot, Dailymotion, etc. are all blocked. A lot of smaller blogs and websites specialized on China are also blocked (Peking Duck, China Digital Times, etc. ). Gmail has a lot of issues, Google Cache is unavailable, Wikipedia is censored on sensitive subjects, etc.
For website in China, it is not much better. Sina Weibo (the Twitter equivalent) can delete posts very quickly and censor a lot of search terms. Popular political bloggers often get their more sensitive articles removed (Han Han is a good example).
What are these China-based blogs that deny censorship ? I am quite sure they would be interesting to follow.
