Damn. This guy was a human rights activist and cofounder of a significant pro-democracy organization named for victims of the Tiananmen Square massacre. He was also an MSS spy reporting to the PRC on the activities of those who joined as far back as at least 2006.

Let me clarify one thing about our draft law to detect online child sexual abuse #CSAM. Our proposal is not breaking encryption. Our proposal preserves privacy and any measures taken need to be in line with EU privacy laws.
