Thanks for sharing. I have to say that the article has a heavy slant towards why we should be concerned with this policy (and we should, there are some very valid questions raised), without addressing the elephant in the room, of Chinese government interference in Canada.

It doesn't help that the authors get some very easy details wrong, like:

The pushback is in reaction to the New Policy on Sensitive Technology Research and Affiliations of Concern (hereafter New Policy) announced by the ministers of Health, Public Security, and ISEC (Innovation, Science and Economic Development) in January. The policy prohibits research collaboration with Named Research Organizations in Sensitive Technology Research Areas

That should be Public Safety, and ISED.
