this is built by Arduino specifically to sell more Uno Q. You want them to start promoting clones? What product do you make and we'll promote clones of those too.
Chinese clones of Arduinos are normally between 3x-6x cheaper, and if your project uses dozens or hundreds or thousands of them, especially in developing countries, that's a major price delta.
I assume at those scales it quickly becomes economical to design a custom board instead of using modules that are probably seated on cheap custom PCBs anyways.
If you have a bit of time to learn the skills, it’s economical to design a custom board even for 5-10 units. An integrated controller module like an ESP32 can basically just be plonked onto a board with a voltage regulator and used like an Arduino.
