I'm just speaking from personal experience. That example was real, Firefox did not work with hardware accelerated video decode out of the box for me under Fedora, which was pretty high impact with that machine being used for studying. I got it working and it's kept working since, but like I said, it took some tinkering. macOS has its own oddities of course, but they don't impede such basic usage as video playback.
