It doesn't justify her frustration at all. There is no indication she tried to help (e.g. by teaching, explaining the superiority of her method, etc.), ever. Her frustration would be justified if she'd been acting like a senior, experienced person and constantly met with ambivalence or incompetence, but there's no indication of that in this blog post. Her frustration absolutely does not justify her actions anyway so I'm not sure it's relevant.
