I doubt they'll do any overt censoring (eg. "no talking about what happened at Tiananmen Square in 1989), but I wouldn't be surprised if they do subtle manipulation like silently deemphasizing anti-China content, or emphasizing anti-westnern content (eg. infighting, failure of western democracy). The latter probably would probably even good for the site (in terms of engagement) as outrage drive cilcks.
