In my world view, a LLM is far closer to a fridge than the androids of the movies, let alone human beings. So it's about as pointless being polite to it as is greeting your fridge when you walk into the kitchen.
But I know that others feel different, treating the ability to generate coherent responses as indication of the "divine spark".
Note, why would the author write "Email will arrive from a webhook, yes." instead of "yy webhook"? In the second case I wouldn't be impolite either, I might reply like this in an IM to a colleague I work with every day.
For the vast majority of people, using capital letters and saying please doesn't consume energy, it just is. There's a thousand things in your day that consume more energy like a shitty 9AM daily.
This seem to be completely subjective; I write syntactically/grammatically "nice" sentences to LLMs, because that's how I write. I would have to "invest energy" to force myself to write in that supposedly "simpler" style.
It's also actually more trouble to formulate abbreviated sentences than normal ones, at least for literate adults who can type reasonably well.

For me the difference is around 20 wpm in writing speed if just write out my stream of thoughts vs when I care about typos and capitalizing words - I find real value in this.
It would cost me energy to deliberately not write with proper grammar and orthography. I would never want to write sloppily to a colleague either.
