Jason uses his writing and news columns to expose the many injustices in the city’s legislative process and electoral system. He believes that, unless and until there is true universal suffrage in Hong Kong, an accountable government will remain out of reach and frustrations over cronyism and corporatocracy will continue to rip apart the city's social fabric.
Jason was an active participant in the Umbrella Movement of 2014, both as a teacher and a journalist. During the 79-day struggle, he camped out on Harcourt Road and offered pro bono tutorials to student protesters. He contributed extensively to the coverage of the movement in the online edition of The South China Morning Post, which went on to win a Human Rights Press Award in 2015. Jason documented his experience in his book Umbrellas in Bloom and his involvement in the movement remains one of the proudest things he has done.
Since the Umbrella Movement, Jason has given guest lectures on Hong Kong's pro-democracy development at:
- Columbia University (USA)
- New York University (USA)
- University of California, Los Angeles (USA)
- University of Toronto (Canada)
- York University (Canada)
- Thammasat University (Thailand)
- Chulalongkorn University (Thailand)
- University Hong Kong
- Chinese University of Hong Kong
- Hong Kong Baptist University
In 2017, Jason was among eight human rights activists around the world honored at the Movies That Matter human rights film festival at The Hague.
