I would maybe understand enforcing that requirement if it was effective in protecting the content, but it isn't. 4K content (from UHD blurays and various streaming services) is widely available to pirate, and VLC doesn't care what kind of cable you're using.
Speculation on my part but I wouldn’t be surprised if those kinds of requirements are mainly there to appease motion picture industry partners who Netflix is licensing content from.
Furthermore, given the long experience the people of the release groups in the piracy scene have in fine tuning video codec parameters for optimal balance between quality and file size, and choosing video codecs that can be decoded on a wide range of devices, I think it is highly probable that many of the people working on the technical side of these things at Netflix have had roles in various piracy release groups prior to having come to work for Netflix.
Not saying Netflix would actively seek out piracy release group members to hire them. In fact it’d probably count as negative to openly state any kind of involvement with the piracy scene, and especially to mention having been part of a release group. What I mean is just that the people who were members of these groups have both the skills and the technical motivation to work on these same kinds of things for Netflix.
Quite likely, but why I, the end user, would ever care about that?
it just degrades my experience.
And those partners require it not because it protects something but because they make money of it by running licensing agencies, so they profit from every compliant monitor and video card sold.
Of course forget about it on anything other than windows (maybe mac?)
How do I check that ?
