There was something of a to-do a couple years ago when some researchers were trying to see how strong encryption satellites were using and whether they could break it and discovered that a number of of satellite operators weren’t bothering to encrypt things at all.
A new study from the University of California San Diego (UCSD) and the University of Maryland has performed the most comprehensive public exploration into geostationary (GEO) satellite security yet, logging large amounts of unencrypted data being broadcast across 411 transponders on 39 GEO satellites, which were intercepted with a simple commercial-off-the-shelf satellite dish costing a few hundred dollars.
Yeah, wtf is going on. GPG was released in 1999 and encryption existed before that too. https://www.ssldragon.com/blog/history-of-ssl-tls-versions/
How is this unencrypted

Wow. Amazing. I basically encrypt everything by default because I’m so paranoid. Sometimes multiple layers of encryption
