Earlier in the article, the author does call out that it's bad code, so he's not entirely blaming these companies. Anyway: You should not be afraid of thinking about what each party could have done better. Not just yourself, but other people too. When I look back on times where I only blamed myself for prod issues, it was less of a learning experience, and more focused on beating myself up for no good reason. That approach shows that I'm afraid of the consequences, and it's an effective way to feel isolated from the team instead of improving.
