I don't think it is a matter of being selfish or all about her. She lets people do what they do so long as it doesn't cause her problems. Ruby was causing her a lot of problems as was Jaune and Blake tried to downplay the actions of the White Fang who have caused her a lot of problems. Yang and Ruby's relationship and their last names have not caused Weiss any problems as of yet, so she would not feel any reason to intrude.
