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.
Yeah, this is a great approach if you're already at war with a country.
If you're not and they're still allowing your planes to fly through their airspace then this is a great way to ensure that they lock your (and your friends') planes out.
