Unfortunately, sometimes someone becomes a bad example. That doesn't make them a "scapegoat", the favored defense of people like that.

A scapegoat is something that takes on all the sins of a lot of others who skate free. If Masliah is the only one who ever suffers, then he IS a scapegoat, but if this article serves to uncover a lot of other bad actors, then he's not. And if his example serves to warn a lot of other scientists to clean up their acts, then his suffering is a benefit.
