From what I remember there were a combination of things reported about Mr Goodson. He didn't make good on promises and didn't repair or make good on warranties. Later he did design some interesting/innovative stuff and tried to make these the best possible. However had a personality somewhere between a televangelist preacher and used car salesman with a twinkle of "southern charm". The hype was palpable which put a lot of people off (especially if you're from somewhere other than the USA). If you've seen any of his videos promoting his gear he usually had a "player" who seemed more like a "shill" at an old fashioned patent medicine show coming up to the stage and claiming the medicine cured him of Cancer, TB, etc.
Still doesn't mean some of his gear isn't good, he's just... well, what he is.
