It's an interesting subject. If not for Beijing's heavy hand, could Chinese internet companies have flourished much more and become international tech giants? Maybe, but there is one obvious counterpoint: where are the European tech giants? In an open playing field, it looks like American tech giants are pretty good at buying out or simply crushing any nascent competitors. If the Chinese did not have their censorship or great firewall, maybe the situation would have been like Europe, where the government tries to impose some rules, but doesn't really have much traction, and everyone just ends up using Google, Amazon, Facebook, etc.
