The Chinese government is striking against US companies it can't beat
It beats some - Baidu (and the firewall) has made Google rather irrelevant from a search perspective in China, piracy has neutered Microsoft. It keeps Apple at bay through the press accusing them of various things, but they're a pretty small percentage of the Chinese mobile market anyway.
They haven't found a way to beat Qualcomm yet, designing your own mobile chipset is not at all easy, and even using home grown standards like TD-LTE for in-country if they want to sell their products to the rest of the world they need to use others' patents on LTE, GSM, etc.
So let's accuse them of being a monopoly (which they are) and abusing it (questionable) and threaten them with huge fines. The thing is, if they're accusing them of charging too little for their patents, what is the remedy - let's fine them but then make them charge more for their patents to make up the difference? I don't understand the logic here...
I'm rather surprised they haven't ever tried to strike Intel in this way - maybe Intel quietly came to some sort of arrangement, or maybe they're next on the hit list.
