In a very twisted way, you could say that Blake isn't a traitor to the White Fang. Blake grew up with the original group, the organization determined to achieve equality for the Faunus. The new leader however has different goals in mind and doesn't plan to stop at equality, but wants Faunus to be the superior race by destroying humans (from what Weiss said and Blake did not disagree).

As a result, the new leader is a traitor to his own group because his ideals go against what the White Fang once stood for, betraying his own members. Blake left as a result and still holds true the ideals of the original White Fang, honestly seeking equality for Faunus and if that means stopping those that seek to harm people, then that is what she must do.
