Maybe this is the reason he did not appreciate people revealing his identity online (basically DOXing him for fun, some journalist did it if I recall correctly). It really sucks when somebody that is trying to do well (stopping the WannaCry Ransomware as he did) is detained, even though we don't know more details at this points, this hits him rather personally and probably not for the good, I am very sorry for him and I hope he gets out soon and that all is well.
