I did say attack, DDOS is often used to pressure/blackmail others. Not always monetary. It is a common MO of state backed hacking groups in North Korea for example but also in China.
Interestingly Baidu relies on the American company Cloudflare to supply DDOS protection and other services to Chinese websites. Now why couldn't Cloudflare just enter the Chinese market under their own brand without a joint venture partner like they have in every other country in the world? Oh never mind, I forgot free trade only goes one way.
