Interesting but the internet protocal will work over shortwave. Not a lot of bandwidth, but it will work.
As will DRM, which has limited data capability including EWF - Emergency Warning Functionality which is intended to convey emergency inforamation. There is also a digital program guide that allows listeners with suitable radios to schedule and record program material for a later time. Essentially it is digital radio with most of the same features as we’re accustomed to over the internet, but at a much lower data rate. So no videos, no big graphics but for basic text information, news, event or rally information, etc it would be quite usable.
And the beauty of shortwave is, it doesn’t have to rely on any US-based infrastructure - no internet, not even AC power. Put a transmitter wherever in the world you want to and aim it this way, I was even hearing Algeria and Morroco on longwave the other night! Sure it can be jammed just like during the cold war but there are countermeasure for that.
We may well be at - or get to - a point where the only secure communications platforms are those that are not under the control of the US government. Just like in all banana republics! Except it will be us behind the iron curtain this time...
