It would be nice if one of the big shortwave operators could datacast these packages to the world as a public service.
If you've already got a Linux system, the Debian openvpn package is under 1 MB and at 50 kb/s would take under 3 minutes to download. I don't know if openvpn in particular is suitable for people who are trying to evade their government, but would whatever features it is missing add substantially more size?
Of course then you get into needing software to decode the more advanced encodings; maybe start with a voice transmission explaining in plain language how to decode the first layer, which gives you a program that can decode the second layer, or something.
Starting to sound like an interesting project.
I'm not saying that makes the problem easy, but I'll say that jamming isn't a very strong defense.
Though the bigger issue here is probably bandwith. It's hard to be both long range and data dense. There's probably easier ways to distribute this. Hell, both Koreas are known to transport different things via balloons.

[1] It is also why projects like Tor and Signal get funding from RFA. Maybe the US doesn't want encrypted services here, but if anything, it's for the same reason they do want encrypted services in other countries.
Seems like it was used way back in the cold war (and even then not blocked/jammed) and I'd guess that current authoritarian regimes would perhaps not bother considering how few could use it.
(1) It's usually around 11500Khz
(2) 4625 Khz
These broadcasts were shut down in the early '10s but ironically one of the masts is still in use by Radio Caroline, the former pirate who broke the BBC's radio monopoly by putting their station just outside of UK territorial waters. Their 4 kW goes pretty far given the site's previous role, heard them as far away as the Lake District.
But they recently switched to a much cheaper and more effective jamming program: Trump [1].
