$BB Someone sent me a private message yesterday. Why did I short BB?I didn't want to say this, but I felt I needed to help someone.There were two messages in the market yesterday.1. Weimar in China has achieved cooperation with BB.2. BlackBerry sponsored a university in exchange for QNX talent.Let me interpret it.1. China's Weima is a small company that only sells 20,000 cars a year, and the price of the cars is between 30,000 and 120,000 RMB. Many Chinese people don't even know about this company.Although working with BB, it doesn't work?Why don't BMW, Volkswagen, Tesla, Mercedes cooperate with BB?Because they have their own system, BB's system they will not use
