Well it is easier to leave this forum than it is to leave the organization - and the ease of leaving - or returning - has nothing to do with "truth" but more to do with the exercise of organizational power and control.
Groups, in their many and varied forms, exert enormous influence over humankind's behavior. The JW organization is small fry in the larger scheme of things and its members and ex-members alike are even smaller fry still.
SBF may have returned to the "congregation" - but he will never be the same man he was when he first left 8 years ago. His thread outlining his recent attendance at the District Convention was the work of a man who is probably not going to be at peace regardless of where he parks his bum. We hanker for what makes sense to us and what makes us feel most authentically connected to others. And sometimes we do this doubts and all.
I cannot judge anyone for feeling drawn back, whether it be to JWs or some other organized religion. It is beyond reason, I think.
I valued SBF's contribution on this forum because he added a note of caution to eager predictions of the Watchtower's demise. Whilst alternative points of view are scorned within the organization, they find a place here, albeit an at-times uneasy place. Even "open" forums can be hard on dissenting voices, right?
A sober, if cautious voice has had the decency to say, "Goodbye" - and as with anyone who says, "Goodbye", reactions to it are varied.
