The author’s product is based on folks accepting this premise and seeking tools to do better.
I do think the setup to get to the substance is a bit long and indirect - but it’s not a given, especially at series B/C startups that folks think about production monitoring as part of the QA process so I do like to see more pieces on that.
Is that a problem that actually exists though? I've certainly never encountered it, as the types of teams the are strict about good pre-release testing are also the types of teams that are big on observability.
Often, when someone looks like they are “willfully misinterpreting” something, they are actually presenting uncomfortable implications or experiences of how a phrase is put into practice. Right or wrong, it is irritating to listen to.
Is it worth enduring your irritation in order to see if someone is meaningfully correct?

“tested” is not a binary state. Code could always be better-tested —- otherwise why would you have hotfixes?
DevOps and Observability are well described disciplines. I don't know anyone who has uttered the meme "I don't always test, but when I do, I test in production" who meant that monitoring, observing and reviewing prod behavior is bad. They invariably meant that they were rushed to release things in prod before it was adequately verified to ensure your customers don't have crappy experiences.
