What devices use this chip? Has it been enumerated anywhere?
A lot of devices are based around the ESP8266 / ESP32 Here is a site with a very likely VERY incomplete list
https://templates.blakadder.com/esp32.html
In addition to what others have said, ESP32 is often used by hobbyists, like a more powerful Arduino. These devices are extremely versatile and cheap. I have several of these in my home automation and this is very bad news :(
There's a billion, gonna be a long list.. I'd do some research on your devices and see if any of them use the esp32
