There's so, so many different reasons in the real world as to why/how details like that end up in front of the customer.
Is OP happy to work for Satan as long as he appears grammatically accurate, polite and concise?
Alternatively, OP is a nightmare to work with because every single other role in the company has to do things in exactly the way the engineers want, otherwise they're careless morons.
To quote Wikipedia:
”Nontheistic Satanism, as exemplified by LaVeyan Satanism (practiced by the Church of Satan and First Satanic Church) and The Satanic Temple, holds that Satan does not exist as a literal anthropomorphic entity, but rather as a symbol of a cosmos which Satanists perceive to be permeated and motivated by a force that has been given many names by humans over the course of time. In this religion, "Satan" is not viewed or depicted as a hubristic, irrational, and fraudulent creature, but rather is revered with Prometheus-like attributes, symbolizing liberty and individual empowerment. To adherents, he also serves as a conceptual framework and an external metaphorical projection of the Satanist's highest personal potential.”
You see, Satan is not just a biblical figure, but also the average IT company.
OP is not being literal. Satire and the interpretation of it are important for a healthy and nuanced world view and discourse.
