If you're going to be using USB drives anyway, then using them to move files into the country would be faster.

More dangerous though. You'd need something like truecrypt, too.

btw, veracrypt is the name if the follow up project. truecrypt shut down over a decade ago rather abruptly, so anything labeled truecrypt today is suspect as either out of date or potential malware.

Nah, just drop a few thousand 1GB flash drives from a plane. Load them with a tor browser, a wireguard client, and instructions on finding a remote exit. Only one copy needs to survive and it can spread very quickly and irreversibly by foot.
