If the activities were truly cool and impactful, and not illegal or unlawful as you suggest, wouldn’t it be possible that the suicide could be due to a culture of not speaking out and then left to deal with the after effect of guilt? A slanderous retort vs a different lens to review the events isn’t helpful
I seriously doubt the GP (who was proud of their work) was one of the suicides. If they were, the mere fact that they are able to post here after taking their own life would be the far bigger story.
