The little information given suggests DW agreed with 'something'. It was very vague, as expected if there is risk of litigation. What he volunteered to do as a result of this vague agreement is what also unclear. How much say he had in stepping down without any reasons given is what is missing. I have seen 'personal reasons', 'spending more time with family', even 'time for a change', but in this announcement no reason was given. That is what scares me.
