TWI has changed a little bit during the recent years. But their change its only towards recover the "good old days" of VPW and PRE-LCM. VPW is still the main figure and the functioning of the organization and psychological abuse towards people persists. They're not willing to apologize to people; they only ask them to forgive and move forward "in love" . It's sad, but they demand greater maturity from the "average" believer than they do from the leader. Forgiving someone does not immediately mean restoring the relationship or psychological healing.
Btw, those letters demonstrate the Victor Wierwille was indeed a cult leader who used (at least) emotional abuse.
I am listening to Steven Hassan's most recent YT video. Which includes an interview with Nori Muster, who had been involved in the Krishna cult and wrote a Cult Survivors Handbook.
