编程随想被判刑，他怎么颠覆国家政权了？

On February 10th, Runn Xiaohuan, a citizen of Shanghai who uses the online name "Program Think" was sentenced to 7 years in prison for inciting subversion of state power by the Shanghai Municipal Court. Program Think is well-known on the internet because he created an open-source blog containing his recommended books, his political comments, archives of public events in China, and a chart of the political-business relationships of the Princelings. These contents had a significant impact on the internet, and finally, he was discovered by the authorities and sentenced to prison.

What is the "Corpus Delicti" or body of crime of Program Think? What crimes did he commit? And how did he subvert state power?
