On “Why do I distrust people who talk about Clean Architecture?”
Regarding PackIT - it would be fair if you'd have linked back the video of the person who did record and implement this, explaining in-depth all the pros & cons, tradeoffs, decision etc.

Maybe then you'd have realized why some parts are (or aren't) using the particular design patterns, structure, where the tradeoffs been made etc. and why it's even clearly mentioned that's a simplified sample to just give the guidance to such approach. But yeah, it's easier to just post an arbitrary link, yell that someone uses buzzwords, fork your repo with custom comments acting as a grandmaster (once again, without referring at all to the original content) and start bashing and swearing :)

Hey,
Feel free to check out a "mini-course" (almost 9 hours) made by a friend of mine about CQRS, CA and other fancy buzzwords - maybe this will help to clarify some of your answers :)
