Near, thanks. I'd had it explained to me, but had long since forgotten.
It was very different to go there in person. I expected an undercurrent of political unrest and dismay with the things like censorship. It really didn't seem like I met anyone willing to vocalize serious displeasure.
As for why people accept the situation, one can probably start with "Nash equilibrium" (I chose not to use the term "prisoners' dilemma" as that could project uneeded connotation in this context).
