From what I recall, the ESP8266 was originally just a module designated to provide WiFi capabilities to other circuits, but over time, hobbyists discovered that it had much more potential. Its incredibly low cost sparked its popularity. Espressif did an excellent job of designing the ESP32 to accommodate the demands of the emerging audience. But I could be mistaken; I might be missing a part of the story.

> The ongoing US-China chip war has created a situation where users hesitate to use Chinese chips, wary of ending up like Huawei's customers. Without this scenario, Espressif chipsets might have enjoyed much greater popularity.

These chips are intricate enough to potentially contain backdoors. While it is something I never thought about with respect to Espressif, it does seem plausible that they could be a target.
