I think the point of the article is that most of the arguments made against PHP can be made toward any other language as well (i.e. you can write insecure code with it), so the defences can be made for any language as well.

It's unfair to say that a vague defense to a vague accusation is invalid. If I said you were the worst ping-pong player in the world because you lose some games I think the arguments you listed would be a valid defense.
