No, I don't understand why he would.
Nothing there was intimidation. Pretending it is intimidation is stretching crudility. The fact that he got arrested over this is straight up nonsense, IMO.
All the posts read like blog-style posts, and there wasn't any aggressive language used there at all. He also mentioned he was meeting with people to resolve the issue through legal means in the posts.
I suspect the owner who owed him money was acting maliciously.
