Only time will tell but the article notes that it is likely that this change is for publishers, not for end users.

I doubt that we are going to see many third-party emulator because of the ROM issue. To my knowledge, most consoles and all computers will have copyrightable ROMs built into the system. Given the relative scarcity of old hardware, equipment, and technical skills to image those ROMs any third-party emulator will attract copyright infringement. That is before you consider imaging software. (While there is a good chance that a person can retrieve a working mask or EPROM from an old system/cartridge, anything disk based will be much more sketchy. Not only do you need working drives to image the software, you need working media and the media cannot be copy protected.)
