I’ve met those types too, though their “nonpolitical” stance would quickly reveal itself to be some form of libertarian ideology (usually one that inflated the societal importance of white or model-minority male cis-het coders at the expense of everyone else).
In this case, as you imply, there’s also a real concern that goes beyond political disagreement into the realm of potential sabotage of the kernel on behalf of the Kremlin.
