People on this board love the idea that anyone who isn't an engineer is an idiot and everything that everyone else does that isn't writing code is somehow worthless. In broad strokes, they think that all people who do people-facing work are charlatans that are constantly trying to hide how worthless they are because talking to people, etc. can't possibly provide value. Then, they (like so), ask you to break down your arguments so they can pin the tail on the donkey that is the logical fallacy that they will use to discount your (almost certainly correct and informed) opinion.

Unsurprisingly, those people are wrong and marketing works.
