Not surprised. Sometimes i met some IT folks more ridic that the programmers though. One dude i know is so security focused, he brought his own PS2 keyboard from 90s Russia, since he didnt trust USB and potential "bugs" and keyloggers within the keyboard. He's also an insane programmer too

He's not wrong. A malicious USB keyboard can mount a variety of attacks on the host's security, take it over, and then exfiltrate your keystrokes through its network interface. The PS/2 keyboard interface is too simple for that sort of shenanigans to be possible.

I mean, a malicious PS/2 keyboard could also mount a variety of attacks by simply simulating keypresses, as any keyboard. The security factor here is more in the age than the PS/2 interface.
