I understand that you are taxed twice, at vest and at sale. My understanding was that the "California gets taxes no matter where you live" applies to the vest (which is taxed as ordinary income), not the sale (which is taxed as capital gains). Your other comments suggest you were talking about a very specific situation, where you started negotiating to sell stock, then moved, then the sale closed. If so, then I'm not sure how exactly it gets treated so happy to defer to you, but that doesn't seem at all like what is being discussed in the article.
