I once saw a very good talk on this exact subject, by someone who was in an incredibly similar situation as that commenter was. IIRC their bit of tech was a tool to triangulate a fairly specific location of a device connected to a wifi network (this was at least a decade ago).

As I remember it the point was basically: there are a lot of valid applications for this concept, but ultimately only one that a defense contractor is really going to care about. If that's who you're making it for they will use it to kill people eventually, even if that's not the plan right now. But also that probably is the plan right now, don't be naive.
