tl;dr Someone filed a copyright complaint against the video. The complaint is substantiated. The article does not say who did it. Trump is of course saying how twitter is biased against him where literally twitter must take down that ad due to the DMCA and them being personally held liable if they didn't. Trump doesn't understand the law, or at least pretends not to.
