There are packages out there that use ESP32 as a "augmentation" chip to do OTA with a main processor being STM32 or NXP. There are also major security flaws and silicon revisions made by ESP32 that makes the whole thing reek of inadequacy beyond anything a hobbyist would do.
ESP32 -> Hobby use only. Don't spin up $500k of tooling and HVM batch relying on a weak CPU that will give you some chance of a complete recall or losing your customer base that took many years to build.
Hobbyists on Youtube and EE Stackoverflow are oblivious to the professional world. Let me know if you would like sources, I don't have time to dig into it but esp32.net is a good place.
