"Widevine Dump":Leaked Code Downloads HD Video from Disney+, Amazon, and Netflix

That's what Widevine prevents: It ensures the decrypted video is only available to proprietary devices and software which agree not to help you rip the video.

At the end of the day you can always record the video buffer in some way or another (hdmi capture device, etc). The problem is that screen recording isn't what you want: it's lossy because you'll re-encode the output of a lossy encoding (at comparable level). You always want an ultra high quality source for encoding (in comparison with your target quality), else you'll amplify artifacts. To not deteriorate the perceptual quality you'll have to do little lossy compression (ie big file size, much bigger than the original encode).

You actually cannot without an HDCP decryptor, which tends not to be sold in a lot of countries since it's primarily used illegally.

The idea with encrypted video such as Widevine, is that any time it passes over an unapproved device (such as an HDMI cable), it is encrypted on it's way to a device authorized to decrypt the signal.

Also, HDMI is a digital format, and you lose nothing in transfer over it.

And this is why I do not pay any company engaging in DRM.

They are trivially easy to buy online though
