You don't get 4K on Windows or Mac either unless you have a HDCP-compatible display, a supported graphics card, and typically the devices will refuse to initiate a handshake due to the locality check failing, or a difference in HDCP version - Unless you have a "smart" TV you're watching in 1080p or lower.
Piracy point still stands: why pay for a service that does not guarantee to give you what you are specifically paying for, and actually goes out of their way to block your access?
Netflix may take away their subscription but they can't take away my Transmission and VLC.
