Netflix now supports TLS 1.3
I noticed they didn't explicitly mention why they feel the need to ensure authentication+confidentiality+integrity for their streams, given that the data they're dealing with is films and TV shows, rather than, say, payment details.As I understand it, they use HTTPS to prevent spying and data-mining by unscrupulous ISPs. It doesn't affect their DRM at all, which would work just as well over plain HTTP.
