It's not blacking out on purpose, rather it's a side-effect of the DRM chain. The DRM content is rendered outside of the UI chain, so it cannot be captured as part of a normal screenshot or video. The same happens on macOS (and even windows) if you try to screen record while watching DRM L1 content such as Netflix, Apple TV+, etc.

Widevine and HDCP can seriously suck it. Look at any torrent site and tell me that it stops piracy

DRM is on purpose.
