The craziest thing to me is a lot of people have been claiming Tether was a fraud for years, but according to this it may not have actually had any issues until ~6 months ago. So they decided to prop up Bitfinex with Tether funds long after they were first accused of fraud, even having that spotlight already shining on them. If they wanted credibility they should have completely separated those two businesses, but I suspect Bitfinex makes more money than Tether, and perhaps they wanted the Tether funds as a sort of insurance policy for Bitfinex liquidity.
