I know it's not a popular opinion here but there's an argument to be made that a censored Facebook would do more good than no Facebook at all. It's not like Facebook being blocked in China is going to spark a popular revolt or reduce government censorship/spying. It could help, for one, expose more Chinese to Western culture and vice versa.
For me however, the strongest argument is that nearly everyone in China would prefer a censored Facebook to no Facebook at all and I'm humble enough to accept that they know, better than me, what's best for them.
