Watching the OG this year I noticed a lot of Kenyans and Ethiopians running for Bahrain. I looked up the Bahrain Olympic T&F team and found that out of 24 total competitors probably 13 (my guess based on names, possibly more if they change their names to something more Muslim) are from one of those 2 countries with a couple more appearing to be foreign as well. I know this has been common practice for some time among Qatar and Bahrain:

Why is this not a real controversy? I've never heard anyone comment on it on any streams despite mentioning the fact that some of the Bahraini athletes are from Africa. No one is willing to explain this. Seems like a morality violation that could be easily latched on to by people that care about the morality and sporting purity of the Olympics.
