Any sort of static analysis/linting tools will occasionally make bad/unhelpful/stupid suggestions, some moreso than others. At any place where I've had to use such tools, I've always had the ability to either tweak the settings, or have a conversation with the people who decide them and make appropriate changes. In this case, it sounds like bad culture and/or bad colleagues are driving this person to despair, and not Sonar as per se.
