If I'm open with you, I lived in Hong Kong for 10 years. I speak fluent Chinese but I also have clearance. Also, I'm very, very careful about what I put on Twitter, so you're just going to see the fact that I've been selective.
I have gotten to the stage where I am very frustrated with the way that, as a professor, I'm constantly targeted by the Chinese. I have attribution. My stuff's been stolen. They've planted Ph.D. students on me. Therefore, I've decided to be more vocal about it. That's what you're seeing.
For me, the problem as I've become more well known is that I'm much more likely to be targeted. I fear that all professors in our field, whichever country they're in—and I wouldn't think that Canada is exempt—will be targeted by, particularly, China because they're really on the hunt for IP, and they have been for many years.
