> Those that do have smaller selections of works for sale... Did you not see the name in the link? More to the point, can you point me to a major music store which does use DRM? I'm not aware of one. Perhaps you've been pirating music so long you missed the shift? It happened around 2009. Here's an article from 2014 about the steps to remove DRM from your pre-2009 library. Tl;Dr, delete and redownload from Apple, no…

Yes, I did see your link. I guarantee you if I search certain songs in there, they won't even sell them to me because of where I live. No doubt all the pop stuff is there but I don't like that stuff. In any case, I don't listen to music very often. When I want to listen to something, I just look up specific songs on YouTube. I never cared enough to "pirate" music but I can tell you that the quality of "pirated" music…

And yet you provide no songs. Fascinating.

The cost of the input is irrelevant. Sell things for money generalized pretty well in basically every other field. It actually generalized pretty well in video too. This is just adding "remove the DRM". It'll be fine once all the old studio execs retire...

The cost of the input affects the cost of the output, which makes all the difference in the world. Let's start with the most obvious: "sell things for money" hasn't worked out that well in music. Streaming services (with DRM) are 83% of revenue in the music industry now: https://www.businessofbusiness.com/articles/vinyl-record-sal... The price of music is dramatically lower. Its consumption model is entirely differen…

First, streaming services charge people money and sell them a thing: access to music. Not liking it won't make that different than movie tickets.

Second, the price is identical. Streaming providers charge $10/month (or very close to it) regardless of what the content is. Also, albums when new are $10-$20, and movies new are $10-$20.

The majority of media-based DRM implementations are completely bunk and fundamentally broken. You — yes, you, reader — are able to take advantage of DRM implementations and break their fundamental premise without much effort But, apparently not Widevine and not the kind of HN reader who wrote the article. They spent weeks trying to extract the key and failed. The article is a story of their failure.

That's one way of looking at it. Who says you need to extract the key for playback?

The thing with the key is also checking if you're licensed, and negotiating with the OS/GPU/display device to prevent you from screen recording it. So the key isn't useless. It doesn't stop you from pointing a camera at the screen and recording it that way, but stuff like Cinavia can stop that too. So, the key does matter.
