An ambiguous phrase - I was not criticizing you but only advising you read his historical statements on databases before engaging. He has wasted a great deal of time of other people.
I am not the person you originally replied to but you (again) commented like I was. My comment was about how your comment erroneously targets the wrong person because you thought you were replying to one person when you were replying to another. You did it again in your previous comment hence my serious question.
