They are both just data being made hard to read, though. You could pretty much sum up the "risks" of encryption as: you want to read some data that someone else didn't want you to read. Which means you might fail to detect something, or fail to prove something as easily as if you could read that data. While we could enumerate specific examples of scenarios that fit the generalization, I think we are talking about something pretty narrow. It is also not really a new problem. Historically communication has been impossible to snoop on at scale, and encryption exists to maintain a semblance of past privacy in the present.

Lol not sure where I want to take this and it's getting pretty late...
