I'm a network engineer with a lot of two way satellite experience. You are not only wrong but you are so grossly wrong that you should be ashamed of yourself and delete your post. Please go read some basic books on cryptography (start with Schneier) before spouting absolute nonsense. Satellite is no more or less trustworthy than licensed point to point microwave, using wifi in an urban environment, or sharing TDMA timesliced bandwidth on a DOCSIS3.0/DOCSIS3.1 coax network segment. All of which are media that can potentially be intercepted and rely on properly implemented crypto.
