BTW. Netflix is in the process of transitioning to TLS (https) transport. Not because they need it for any reason, but because shady advertisers keep snooping connections and using that to profile users. Netflix is tired of being accused of selling user data. My understanding is that the movie was already encrypted, but that stream could be fingerprinted to identify which movie it was.

Using TLS is a lot more expensive so that costs them money, so I have to respect them for that.

Grandma's TV is still unencrypted, but anyone who updates their client is protected.

They do have to deal with a whole ton of legacy clients.
