I feel the need to clarify two things involving the man who went to jail for "trolling" that you clearly missed.
1. What he did was far beyond trolling. Applying trolling to what he did is the same as saying if I go out and have a shoot out on the streets of my town, and people react, I'm a successful troll irl.
2. His imprisonment does not in any way relate to free speech. He was harassing the families of the deceased people with incredibly offensive attacks. He was not expressing any kind of opinion or otherwise, you cannot apply free speech to what he did.
