1- AFAIK, Espressif uses closed binary blob for WiFi so the channels could not be tampered with. Still, they need FCC regulation for their whole product in some jurisdictions.
4- I don't think any kind of crypto could be reasonably mined on these MCUs.
Different territories have different channel restrictions. As a result, some countries have access to channels that other countries do not. Setting your wifi up as if it is in Japan gives you a couple of channels you are not legally allowed to access in North America, for example.

Wouldn't changing the locale settings defeat 1-?
locale? If you mean some config, I think the binary blob should handle WiFi protocol to the spec (BTW, It's a freeRTOS application IIRC)
