What's wrong with Dave Weiss's character? I'm not aware that he has any kind of bad reputation.
He seems to remain willfully ignorant by carefully controlling his arguments with AI and carefully arranging other proofs & arguments in such a way as to direct attention away from the holes in his arguments. There was also the time he was called out regarding a weakness in his app that could easily compromise many people's personal info, or something like that, but he did nothing, didn't take down the app, and even supposedly used globe earth math formulas in the app for it to work using GPS. I just don't like it when there may be monetary incentive involved from views and buying apps and stuff. It encourages such people to disregard truth for the sake of more views and money.
I just don't have a good feeling about him.
