"Well if you're going to complain that a guy "[does] not sound like someone who studied computers or technology" it would be more convincing if there weren't several well-known instances of you demonstrating a lack of knowledge of computers and technology."

but that is not the real "complaint". Dvorak just says that led him to dig deeper. The accusation (or "complaint"if you will) is that Kundra fudged his credentials. It doesn't matter how technical Dvorak is for the truth or falsity of that statement. Attack the accusation (which is very specific and can be easily disproved) not the accuser.
