Here is my proposal based on comments above to replace the first two sentences of the Disputes section:
In 1991, Werner Erhard “… vanished amid reports of tax fraud (which proved false and won him $200,000 from the IRS) and allegations of incest (which were later recanted).” [ref to Time]  The March 3 1991 60 Minutes broadcast of these allegations was later removed by CBS due to factual inaccuracies.
