Tam: Firstly, the 'Green Dam' [an internet filtering system] incident in Mainland China has aroused the attention and dissatisfaction among the IT industry practitioners in Hong Kong. Together with IT industry practitioners, I have drafted a joint petition letter, and finally pressured the Mainland Chinese government to shelve the implementation [of the 'Green Dam'].

Secondly, I said "No" to "Internet Article 23." I demanded the Hong Kong government to first arrange public consultation for the Copyright (Amendment) Bill 2011, including whether it should exempt parody work, and present the bill to the Legislative Council only after the society achieves consensus.

Mok: When the Hong Kong government consulted about COIAO in 2008 they mentioned a proposal to include mandatory filtering by internet service providers (ISPs). They said Australia is already doing it. I investigated with the Australian Chapter of Internet Society and found that to be a false claim, and challenged the Government about it. The government backed off, and took away that provision.

When the Chinese government tried to implement 'Green Dam' in China in mid-2009, I worked with local information security professionals to "dissect" it and offer the world to see the truth, that it is a surveillance software. This was widely reported by international press. The Chinese government eventually backed down.
