No personal experience here, either, but word on the street last year was that he was widely disliked outside of Zappos.
When I lived in Nevada, he was heralded as the future savior of downtown Las Vegas, having bought up a bunch of dead motels and vacant lots to transform into something new and better. Plenty of "tech disruptor" headlines in the newspapers.
After a few years, when virtually nothing came of it other than a quirky-but-empty strip mall and a clubhouse for his hangers-on to gather in, there started appearing articles about people being unhappy with how things were going, and him in particular.
Never heard about any strife from inside Zappos, though.
