You can argue Blizzard puts profits over free expression (every company does
to varying degrees). It's absurd to say the kid's obtuse outburst, if left
uncensured, saves lives.
That is where the problem comes in, it isn't a single censored outburst by a single player and not a single company doing the censoring. China is using that uncaring greed to ensure that these protests are censored on a larger scale.
