Netflix's entry into the HTTPS party comes as privacy and security advocates are calling on all websites to encrypt all their traffic. The rationale behind the request is that continuous and complete HTTPS protection thwarts state-sponsored attacks that countries like the US and China launch from the Internet backbone. Web encryption is also useful against man-in-the-middle attacks that hijack huge chunks of Internet traffic. In both cases, HTTPS prevents the attacker from surreptitiously injecting malicious packets into the targeted data stream.
