Not sure why your brought up the .us rules since they are much more liberal then the .eu rules and show how silly the .eu rules are.
Because it shows that the principle of having citizenship/location/relevance requirements is not unique to just the new .eu domain rules.
It is a difference of degree, not kind. Whereas the article and many comments are implying if not outright saying that having any restrictions around location, citizenship etc. is malicious and aimed to 'punish' the UK.
