To be fair, the microphone _is_ listed on the specsheet of the LicheeRV Nano

https://wiki.sipeed.com/hardware/en/lichee/RV_Nano/1_intro.h...

I assume they didn't intend to put a mic on the KVM product, but they wanted to make a KVM product, already had this SBC product, which reusing their existing stock of helped keep cost low.

Should they have been more up front about it it? Sure, and it's not great that they had a bunch of security issues in the FW anyway, so not exactly great, but "hidden microphone in a Chinese KVM" lets the mind wander

"hidden microphone in a Chinese KVM" is the correct way to describe what is going on.

"Reusing existing stock" is not a valid excuse. They are currently selling this device without advertising that it contains a working microphone.

A working microphone and recording software and hacking tools like aircrack-ng on an otherwise stripped-down OS image...

Vendor BSPs are horrible, it would not surprise me if tools like that were included with it.

I used one that included everything in C:\Users\<actual dev's name>\Desktop in it.
