Yahoo doesn't seem to be at fault here... (Score 1)

MNCs have to adhere to country laws and policies when operating in that country. If it was illegal to leak the communist party agenda, then the journalist was an offender. Cell phone companies have been cooperating with governments of democratic countries too to track down offenders who use modern, hard to trace technology to their advantage. Yahoo can't be berated for helping the government, just because China is communist. If our dear Mr. Shi Tao wanted to send the text of an internal Communist Party message so badly and also not get caught, he shud've taken "precautions" such as spoofed email name and contact, spoofed IP and MAC addresses and the usual hacker stuff. Without these, he was a sitting duck :-)
