==Why it is a problem==

~~DRM, by definition, is~~ designed to ~~make content less compatible with devices. This means there is~~ a ~~higher likelihood~~ of ~~software or hardware refusing~~ to play content due to buggy or overly restrictive DRM. For example, with the aforementioned Netflix HDCP requirement, it is not enough for the display you intend to watch the content on to support HDCP—all monitors connected to the system must support it.<ref>{{Cite web |date=2024-02-24 |title=Netflix requires all monitors to be HDCP 2.2.

A device in user's legal possession designed to act against their owner's intention constitutes a case of [[Right to own|eroded ownership]].

Such ~~requirements~~ are not always clearly disclosed. When they are, they are often buried in the Terms of Service or, in Netflix's case, require navigating through multiple FAQ pages. Furthermore, some content may surreptitiously install DRM without the knowledge or consent of the user, such as in the Sony Rootkit scandal.<ref>{{Cite web |date=31 Oct 2005 |title=Sony, Rootkits and Digital Rights Management Gone Too Far |url=https://blogs.technet.com/b/markrussinovich/archive/2005/10/31/sony-rootkits-and-digital-rights-management-gone-too-far.aspx |url-status=dead |archive-url=https://web.archive.org/web/20150317040653/http://blogs.technet.com/b/markrussinovich/archive/2005/10/31/sony-rootkits-and-digital-rights-management-gone-too-far.aspx |archive-date=17 Mar 2015 |access-date=20 Apr 2025 |website=Mark Russinovich's Blog}}</ref> Such software may contain exploits that can compromise the security of the user's PC.<ref>{{Cite web |last=Krebs |first=Brian |date=10 Nov 2005 |title=Virus Writers Exploit Sony Anti-Piracy Software |url=https://blog.washingtonpost.com/securityfix/2005/11/virus_writers_exploit_sony_ant.html |url-status=dead |archive-url=https://web.archive.org/web/20061116191907/http://blog.washingtonpost.com/securityfix/2005/11/virus_writers_exploit_sony_ant.html |archive-date=16 Nov 2006 |access-date=20 Apr 2025 |website=Washington Post}}</ref>

A DRM technology is, by design, an artificial restriction of capabilities of a device, either in general or only for certain protected types of content. Such restrictions need to be effective when the device or a copy of a creative work is in user's physical possession. And physical access allows for many techniques of analysis and reverse engineering that may be used to devise a way to circumvent the restrictions. Therefore to be effective, a DRM technology needs to withstand the techniques available to consumers. This presents a serious engineering challenge, seemingly with no perfect solution, because solutions to date have failed or compromised various additional functions in different ways.

For example, Netflix requires HDCP DRM for playback of its video content in advertised quality. And on multi-monitor systems HDCP only works if ''all'' connected monitors support it, not just the one that displays the video.<ref>{{Cite web |date=2024-02-24 |title=Netflix requires all monitors to be HDCP 2.2.
