Wait... That's historically true, isn't it? The Qin Dynasty unified China's writing system in an effort to unite the disparite cultures (not to censor them).
I interpreted the statement as propaganda in favor of the simplified writing system, which originated with Mao Zedong's government in the 20th century. Additionally, it is worth noting that the important of Chinese unification is part of modern Chinese propaganda, and that separatist movements (e.g. in Tibet) are routinely oppressed; Taiwan is a hot-button issue for the same reason.
Traditional was already unified. Simplified was a simplification (to increase literacy levels), there is no evidence that simplified was a newspeakesqe version of chinese
Lets not confuse history and propaganda.
