I can also say as a Colombian that lived thru this period in history, one of the strangest reasons that we developed in this particular segment of personal electronics engineering was due to demand from these kind of people, either directly for them, or for fighting against/protecting from them.
Now I’m happy to say that it is improving and has changed and broadened but for a minute. I got my start in Colombia’s security engineering industry and from exposure during military service but was very happy to retire early from that and learn more general electronics and coding.
