Are they breaking Widevine? Are they circumventing it? If the end result is an analog audio signal and (a ton of) RBG on/off signals - why can’t I as a normal consumer capture it using some store bought gyzmo?
Absolutely - modern pirates are extracting the digital streams with the DRM removed. However they closely guard the methods of operation because once the exploits or compromised keys are known they can be revoked and they have to start cracking again. They likely have hardware with reverse engineered firmware which won’t honour key revocation but still needs to be kept upto date with recent-ish keys.
For example the Blu-Ray encryption protocols are well enough known you can get things working if you have the volume keys. However getting hold of them is tricky and you have to be careful your Blu-Ray doesn’t read a disk that revokes the old keys.
For streaming things are a little easier because if you get the right side of the DRM you can simply copy the stream. However things like HDCP and moving DRM into secure enclaves are trying to ensure that the decryption process cannot be watched from the outside. I’m sure their are compromised HDCP devices but again once their keys get leaked they will no longer be able to accept a digital stream of data (or may negotiate down to a sub-HD rate).

Basically, media cannot truly be DRM because: (1) it ~has to be converted into data that screens and speakers can display (2) ultimately if it’s fetching widevine encryption keys, those keys are somewhere in your device and can be retrieved
So yes, you can do it. A “capture card” is such a “gyzmo” — but often, you can just rip using software, i.e. record the decoded stream

To put it another way:
Therefore, any media that is viewed on your computer is clear, on your computer, in a realm that you control.
This is also why ad blockers work. You can send me ads, or requests to fetch ads and my computer just ignores them.
Companies will never be able to stop this, cause at some point you can always just intercept the data feed at a hardware level and reconstruct the stream.

If they have their way they will. All the tech bros are pushing for trusted computing platforms.
Imagine a world where most/all computers are as locked down as an iPad. That’s what they seem to want.

I might be asking a dumb question, but why can’t the companies host their ads on the server-side? Do the ads have to be on my computer for me to see them? What does being on my computer even mean in this context?
Sorry if this is a stupid question

it’s not even hard. It’s just to much work, if someone else is doing it for me I thank them with thought and prayers (and sometimes I donate money)
Funny enough sometimes I’ll download shows that I already paid for (lile Max ot Netflix) just becaus VLC is great and my TV is not
