Are you young enough to use TikTok? TikTok not only sucks up a lot of information about you, Mr. Jackson, but also shapes your opinion through very cool, short pieces that target you specifically, based on an understanding of the kind of stuff you would buy into. It's an extremely sophisticated and subtle mechanism.
In terms of WeChat, the language of my home is Chinese. I use WeChat every day because it's the only way I can communicate with my former colleagues and classmates from my education in China. It is clearly very sophisticated in the same sort of way. It sets out messages that are pro-PRC, and it's active here in Canada. Ashbury College in Ottawa not only has an Ashbury College WeChat site, but has, for every single grade, a WeChat site to speak to Chinese parents in the Chinese language.
I would never put anything on WeChat that would be in the slightest way political. You can see that the degree of specificity of this technology—I don't think it's from humans, but from algorithms—is staggering. We should be worried about it.
I was very much involved in the Kenny Chiu matter, in which similarly anonymous Chinese sources were very sophisticated in their manipulation of people's attitudes towards this candidate.
