They find devices that are easy to hack (and I mean rip and tear) and extract the decryption keys from each of them, from what I have heard cheap chinese tvs and set top boxes, they extract the keys from the chips (hardware hacking, heard some even use microscopes to read the keys by hand), and then use them to decrypt streams, I heard that they catch them pretty fast to they use like 1 device per season. This is why they use mostly stollen devices.
The really shitty thing is that vulnerable devices get blacklisted en masse, so all legitimate users get stuck with 480p video content on streaming services. The Nexus 5 got this treatment, as I understand it, because it was too easy to extract the keys.
Breaking HDCP is a lot easier than breaking the other things. You don't have to attack the torment nexus directly. This is not the most ideal option but it is information theoretically correct assuming your capture rig is set up properly.
I knew of this chrome bug which could allow netflix to be ripped. I had heard it in comments of some section of youtube and I might need to look further into it but its definitely possible.
And it's an entirely useless effort. No idea how it is done but the internet is full 4k rips.

Interesting - do you have any sources to read further?

More easily in the past (I don't think if it's still true for 4K) you only needed an HDMI splitter to bypass HDCP copy protection.
The analog hole is real.

It would be harder to break HDCP and you wouldn't even get the original compressed media content. It's a worse idea.

It's not as easy as downloading a YouTube video though
