I have asked him about the reason he stated for downvoting, he admitted that his reasnoning was not well articulated.
I am more interested in the reason of downvoting. As you say, if one disagrees one may state opinion and/or downvote. All I pointed out was that his reasoning was wrong and inconsistent with his other behavior.
Actually I said my explanation wasn't well stated. The part I was referencing was "No Value" regarding the SCT token.
