I've watched a lot of Jon's streams and stuff and I think "troll" is a mischaracterization. Trolls get a kick from getting people riled up, which definitely isn't the case with Jon.

He is often quite blunt though. He doesn't usually go out of his way to say things nicely and, being somewhat in the same boat, I think this is mostly because he's just sick of seeing the same bullshit over and over. It is frustrating.
