Let him do whatever he wants.
Everyone has the freedom. Now it is up to the community if they will promote him to the DT network. The feedback on your profile was neutral, and you shouldn't bother too much about it. The user Satofan44 joined the forum less than 60 days ago. I don't think he understands how the feedback system works. He has already left five feedback, and three of them are negative. In my opinion, all three are incorrect uses of the feedback system. Moreover, the user has not built his custom trust list yet. While I agree that his technical knowledge is good, I think it's too early to bring someone on the DT network. If he continues like this, it would backfire, and he would get kicked out of the DT network. Just my two cents!
