I immediately assumed the author might have been pretending a bit in order to motivate the article. Self deprecation sometimes makes things more relatable. I bet there’s even a name for using self deprecation initially as an excuse or motivation to make a point, but I don’t know what it is. That said, I’m well aware that opacity is multiplicative, and yet it still caught me off guard before to realize that the commonly used lerp blending mode (SRC_ALPHA, ONE_MINUS_SRC_ALPHA) is incorrect in the alpha channel. Pre-multiplied alpha can also be unintuitive at first, even with a decent mental model.
