You actually tricked yourself into believing this isn’t all about shutting down competition to American companies or stopping people’s (especially young people’s) power to disseminate even remotely left leaning views that could gain traction and threaten the oligarchs.
I mean even the politicians who back this bill state as much, so I’m not sure why you think this is about national defense. American citizens are just under as much threat as before, but now they have one less way to express themselves. Ain’t that great. /s
You might not have heard of the formats but you’ve definitely listened to them. For example, Youtube has only served audio in aac and opus for years now. Most instant messaging apps also use opus during calls to reduce bandwidth usage. And those are just some big examples. Basically almost any online service has dumped mp3 in favor of aac and opus since they’re better in every way (in the sense that they have better quality at the same bitrate as mp3, so you can reduce the filesize by a lot and still preserve the same audio quality)
