''The most potentially dangerous have been paid off already''
That did not work with Raymond Franz. The WT is too greedy to pay out enough money to keep disgruntled Bethelites quiet. It would take huge sums of money and perks which could be traced. If one of the "most potentially dangerous" ex-Bethelites discloses seriously damaging information, the WT will direct the local congregation to form a judicial committee and disfellowship the rat for causing divisions and apostasy, just like they did with Barbara Anderson.
