No, because discrimination in hiring on the basis of race is illegal. It does mean the org should probably not focus its efforts on running a big public pr campaign about hiring ethnic minorities though.
That's all in the general case though, unfortunately it does sound like there was some bad practice in the fsfe specifically this time. There are two sides to every story though. I'd want to hear both before making judgement.
Some folks think that morality and law are the same thing. That the very meaning of "ethics" is "things not on the list of illegal things". And if the law was not involved here or did not force anything to happen, then clearly everything was ethical.
