DRM
A community for the discussion of topics surrounding DRM, Digital Rights Management.
All media that DRM can be applied on can be discussed here, for example books, movies, music or games.
Digital rights management (DRM) is the management of legal access to digital content. Various tools or technological protection measures, such as access control technologies, can restrict the use of proprietary hardware and copyrighted works. DRM technologies govern the use, modification and distribution of copyrighted works (e.g. software, multimedia content) and of systems that enforce these policies within devices. DRM technologies include licensing agreements and encryption.

Widevine L3 is trivial to decrypt at this point, there are even APIs on the web to decrypt it. Playready SL2000 is starting to get much easier to decrypt as well.
Forcing TEE based DRM (Widevine L1 and playready SL3000) would have the potential to cause too much collateral damage. They would almost certainly have to have exceptions some devices. If they intentionally break compatibility on browsers other than chrome, they would probably face antitrust issues.
So it is likely there will always either be a way to bypass or decrypt.
