What other factors are there? The article has brought up none. The reasoning of the matter is this: Uber has few black technical employees, one black employee committed suicide, hence racism. Or is there something else that is missing? You realize that the same argument could be made (and has been made) for female employees? <tech companies> have few female technical employees, one female employee complains, hence <systematic sexism, "bro culture">.
