Is that really plagiarism tho? No, its not.
Copyright is a better word indeed.

Agreed.
Most of this drama is solved by now: Gyrsur lost his DT2-position, he removed most of his abusive negative feedback, he lost the negative feedback from DT on his own account. I'd say case (almost) closed, other than the few remaining negatives left by Gyrsur.
