The difference is that we've always known (or at least assumed) that Mozilla is anti-censorship, but can't assume it's anti-capitalist. Not everyone agrees that capitalism is oppressive, but anyway, that's a technical discussion. They haven't stated "Mozilla is against capitalism because it's oppressive blah blah blah". From the principles that they've declared one can infer that they would help people in totalitarian regimes (any decent organization would).
