So, if I understand this right, you are leaving the KH, because a schmuck (his standing with the elders) got backhanded by the elders for having the impertinence of asking them to speed up his reinstatement process? The WT-org is a cruel taskmaster, always has been, always will be.
Why not leave over something that directly affected you or over a false doctrinal issue- and then make public statement about it?
The elders did that guy a favor- they likely sensed that he wouldn't be able to unlearn ( in 3 or 4 months) his old (now incorrect) WT dogmas and would have made trouble for them down the road, ie, "that's not how we used to do it, that's not how the generation was taught 20 years ago". It's not repentance they needed from him, no, it was 9 to 12 months of continuous brainwashing at the KH.
