Josh have been a member of method for a very long time and has been part of what it is today. Just kicking him out would not be an easy decision. It does not inspire loyalty, if you are ready to oust your veteran members for non-proven accusations. Method should not be blamed for trying to keep him around, even if he was a wierd person. Its not like they helped him do some of the bad things or like that.
That said, i understand why they have cut the connection and they should have slowly done that a long time ago. Said, that he needs to be much less visible or suspended until he has his affairs in order. Would give him a break to prove himself and then return.
