Blizzard dragged themselves into this debate with the disproportionate punishment of Blitzchung and the casters.
Which is really the core of the issue here. By issuing such a disproportionate punishment to Blitz, (for context, people cheating at a similar level of play have gotten away with far less of a punishment), Blizzard have essentially sent the message that going offending China is a worse violation of the rules than actually cheating in a tournament setting.
