I don't really think so, that's not a betrayal, what makes you think that she betrayed? For me I don't really think this a betrayal I take that as a mistake, and we all make mistakes.Yes she did betrayed her, she can move and join a similar start up company and use a her teachings but to steal her clients that's a bit foul for me. She's a snake in disguise who knows if they actually planned everything from the start?
