Just personal view, but some stuff seems only useful for the person doing it as they work through their exit. It's too confrontational to win much sympathy or attention (outside of a restraining order), and just feeds the GB narrative of crazy apostates for those inside.
Hope the guy doesn't come off too badly from all of this. I'm not sure if the original newspaper article gives a fair reflection of events. But don't cross the line into harassment and public order offences deliberately. That's silly.
