Ah, I just reread that article and now I see: "The current and former employees say he inspired a small team of young engineers to develop more secure code, improve the company’s defenses — including encrypting traffic between Yahoo’s data centers" So that makes more sense now, I guess it's possible to spend that much on "encryption". People and processing power are expensive I suppose.
