I have no idea how that's supposed to work. Then what? Plenty of participants to some of those trials have spoken out. That's the end of it. They speak out, we appreciate the contribution to the conversation and add it to the pile of evidence. That's what happens when participants in those trials are identified. They're anecdotes, not much more can be done, the trial data is much more useful.
It's a really bad idea to make strawman arguments like that. It works within the circlejerk, but it makes them look very unprofessional to independent observers. They may as well have been arguing that alien invasion was a likely consequence of releasing the data for all that that argument was grounded in reality.
