a lot of third world countries still use CW for distress calls,

Some 3rd world countries also still use animals for plowing.

Some people in this country actually buy what these people produce.

And some people in this country put jewelry in their noses, lips, ears and
other odd places.

Others go out and buy cell phone/TVs and pay $200+ a month for their
communications.

Some people build model airplanes from WW2 or do needlepoint or collect
antiques as a hobby.

We could write a book full of this stuff.
