Professor, the only thing I'll say is this: I think the control over the data is a more important question than ownership of the data. I'm not saying that the ownership is irrelevant, but I think for the purposes of the topic at hand, the issue is really about control and not about ownership. That's all I have to say, other than repeating myself with respect to the different interests that are at stake. I think some bottom lines would need to be set, for example around data leakage to police and other investigation institutions or agencies. They should not be getting what amounts to public health data under any circumstances.
Professor, what do you say?
