My favorite rust moment was when me and a comrade were out roaming. He spots a base littered with Nazi paintings. I get kinda excited and immediately 180 degree turn to base to start grabbing all of our explosives. As I'm rolling up, my comrade asks, "hey what's a fashy number?". I immediately respond, uhh, "1488"? I hear the 4 beeps followed by the door unlock sound. We were able to take over their entire base without a single explosive on the very first combo we tried.
Stole their shit and converted the base to a gulag (put prison cells up around their bodies/sleeping bags). And of course replaced their signage.
You can do that with GPL. It prevents massive corporations from essentially leaching off your hard work but can still be free value to everyone else.
