To be able to comment on this case, we need to know the situation on both sides or have access to information about the account. Unfortunately, I have too little information to answer your questions.
Oh no, we can comment on it just fine.
You are right, anyone can comment on this situation as they wish and everyone can believe who they want.
They scammed him.
You base your conclusion on the story of one side. As for me, without access to detailed information about the account (or at least a comment from 1xbit), unfortunately I cannot take any side. For me the truth is in the middle and it will probably remain so in this case, if no new information becomes available.
