A contrarian anecdote may help expose an article being false or misleading in itself. For example: a review written by the manufacturer itself, or astroturfing.

First we must determine the validity of the article existing in itself and any motivations or biases in it. For this, contrarian anecdotes are useful. This article seems to miss this point.

Once we can accept the article at face value, then we may hit the biases described.

I would say it is far easier to astroturf a contrarian anecdote.
