One friend who visited Huawei revealed the following information:
1. The computer used by each software engineers is firmly locked in a big case on the desktop, you cannot touch any part of the computer but power button! Therefore a engineer cannot use CDROM, floppy driver, or USB.
2. Huawei has a 300+ person MIS team, which is in charge of checking all outgoing e-mail (1 by 1) to prevent any important information being sent out.
I can see any difference between a prisoner and a software engineer but earning money!
