I haven’t met gates and I agree these days he comes across pleasantly, but perhaps you are not old enough to remember stories of what he was like in his 30s and 40s when Microsoft was younger. He was a tyrant and viscously anticompetitive. As a husband my understanding is that he cheated on his wife (not uncommon I know but still hurtful). He might have become a somewhat better person, maybe, but he certainly wasn’t one when he was making his fortune.
