Please check the textbook - that fallacy asks to accept a claim based on authority. In this case, we have a negative-spin troll (negativeonehalf) spreading FUD about an established subject expert ("a lot of other stuff wrong") with one falsehood after another (paper not peer reviewed, Kahng funded by Cadence, etc). No authority is needed to debunk the troll's claims - they are not supported by anything, basically made-up nonsense.
