China is doing what the U.S. would normally do in an effective anti-monopoly action, if our system was not broken and the government not bought with its guts by billionaires floating in tax-cut windfall.
Now we have entities that have more legal resources than the government, which is a recipe for disaster (and runaway legalized corruption).
China sees what happens when you let money run loose through power structures, and it does not want the same fate.
