I realize you are just trolling us now, but this is a pretty clear situation. This is a group that cherry picks races that do not drug test. Why do they do that? They have great athletes; they could be picking up some extra money in races that do test.
Obviously, some of this is on the race directors. By not testing, they are giving this group (and others, I'm sure) free reign to come in and, yes, steal from clean runners.
I am hopeful that the race directors are ignorant of this, and would be upset to find out that their prize money is probably going to cheaters. And will then hopefully make this sort of thing harder to pull off.
And your strawman of "why should we care" is ridiculous. We care because we want to see the prize money go to non-cheaters. It's pretty simple.
