The article talks more about being able to legally play old games without downloading roms or anything, but that's a different topic from video game preservation. Video game preservation itself is doing just fine though. The vast majority of games are archived online and emulators provide super easy ways to play games that are impossible to find now.
Sure, companies should allow people to play older titles in easier ways, but to say "efforts to preserve gaming's rich history are failing" is just wrong.
