I reached out to them a couple of times, and they asked if I had rfkill installed, I told them no, but it shouldn't matter if it was a hardware switch.
They told me that they would look into it, and then never responded after that.
Interesting indeed! Here [1] is how it allegedly works. Is the laptop easy enough to open and check if the board you have looks anything like those photos?
On the other hand, putting a signal onto disable pins is not exactly a kill switch. The description sounds like a hardware switch in front of a soft kill, which would make it some sort of quasi-HKS. A real kill switch would need to totally cut power to that controller rather than rely on it playing nice.
On the gripping hand, I find it hard to believe they would overlook something that crucial. Eg, if it didn't work, it would /have/ to show up during testing.
I wonder if the chip needs to be tightly integrated into the board and a proper HKS would require cutting signal to dozens of those pins -- something that is perhaps impractical -- so they went for a lesser option.
FWIW, there is at least one more person alleging the same broken functionality [2]
I do have a video of the wifi in action though: https://tmp.thekyel.com/month/wifi.mp4
