To which the CEO was rude and dismissive and threatening. Which is often a sign of having something to hide. I assume the author decided to then verify if the threats were made from a position of strength or weakness.

What tptacek was getting at is that the article is a bit unclear on when the review of DB contents occurred, since the author no longer had access. (But I think it’s just because the author reviewed the contents already before they reported the issue.)
