If you think about it too, the same thing applies to Windows 8 and 10 (which doesn't have a built in DVD decoder, Microsoft's way of saving $2.50 per copy) if you choose not to use that crapware Cyberlink but instead use VLC
Same thing also applies to Blu-Ray discs of course. Must be nice to live in a world where everyone can stream all the high definition content they want, but that place is not the USA.
Actually, the provision in the DMCA disallowing decryption is unconstitutional. There just hasn't yet been a court case with the correct conclusion. It flies directly in the face of fair use, and no simple law can override that.
