Big tech long ago decided that the PC is a problem to them and they want to move to locked-down gadgets.
They can, for example, enforce market segmentation: You bought the DVD in the USA and play it in the EU. Legal, but DRM stops you. Wait for the EU release and pay the different price.
If the content middleman screams piracy, react as if a politician screams child porn. They want something else, but cant' get it without invoking the bogeyman. Hordes of (starving artists/concerned parents) will provide the necessary rope to hang themselves on command.
Ok, but don't they risk discouraging people from buying disks? Who buys disks nowadays anyway?
The real problem with computers and disks is these days most computers do not come with any sort of DVD/BR/UHD drive. You can find the odd one here and there and sometimes in desktop format. But in the mobile space they have pretty much disappeared, except as USB addon. Once apple ditched them everyone else did too.
I had one of the cyberlink bits of software. It worked just fine for 6 years. The drive is fine. The certs on the software however expired. Once that happened no bluray would play at all. They wanted a decent amount to 'upgrade' so I could watch my movies again on my computer. So I used that money and bought some ripping software. So I rip and use things like VLC and KODI to play them now. Which is kind of 'meh' as the java emu layer is not there yet. Most of the time you can pick the right title out of the list. But sometimes (usually sony) they will throw several thousand titles on the disk that are not quite right but have the right size.
These companies have not totally worked it out yet (they are well on their way though). With 100% streaming digital they have a decent amount of physical control, probably prefect pricing, and re-editorial control.
I never made the connection between these two ideas before. Now I am wiser. Thanks for this.
DRM has nothing to do with piracy of even control over end-user. It's all about media companies having leverage over hardware manufacturers of TVs, computers, game consoles, etc.
So media companies want extort money from hardware manufacturers. Manufacturer might choose not to pay, but then most of movies and Netflix (FullHD, 4K) wouldn't play on their devices.
1. Stopping "casual" piracy, that is, stopping a tech illiterate person (most of the population) from simply copying it to another tech illiterate friend (they don't want a repetition of the K7 mixtape era).
2. Create a walled garden were you have a monopoly that you can abuse to extract better deals from other stakeholders.
It's both. Easy generation of pirated copies also vastly increases the number of sources and the speed of propagation.
Disney CEO: "We want a DRM system that will make piracy impossible. Can you do it?"
Developer: "That's impossible, it can't be done."
Disney CEO: "My son is constantly asking for $70 games for his playstation/xbox, so I'm not convinced DRM is impossible. Could you do it if we paid you $300,000 per year? Or do you have nothing to offer the company?"
Developer: "Well, when you put it like that, I'm happy to try. We can certainly make something that doesn't have the holes previous systems had, and that will slow down piracy, initially."
Disney CEO: "Ah, so it might be possible after all...."
In the current world, they are no longer needed, and they know it. But they still have power. So they are doing everything they can to keep up their revenue streams. If they admit to progress, if they try and make a working ecosystems, they are working on something which, at best, requires massive downsizing for them.
So instead they are flailing about looking to construct ecosystems that still have a place for them.
It's reasonable for a non-technical person to agree with a solution that claims to prevent piracy because they have no idea how these things work and their trade-offs. They don't mind it because they don't see themselves as pirates given that they just bought the media and are unaware of how the DRM scheme can backfire on them despite not being a pirate.
Very few people would agree to DRM if the DRM scheme explicitly had a disclaimer "we can, for any reason, prevent you from playing this in the future even on the same hardware that successfully plays it today".
