Isn't it great that we work in an industry where a company like Netflix, which has increasing competition lately, just shares potential competitive advantages like this?

I get that, in part, this is a way to get people excited to work for Netflix, however, the people working on this are, probably, pretty proud of what they achieved and thus like to share it with us, their colleagues at other places of work and they have the freedom to do so because of our industry's great track record of knowledge sharing.
