Encryption is not a crime, encryption protects all of us. Encryption, and especially end-to-end encryption, is an essential tool to protect everyone online. Attempts to undermine encryption are an attack to our fundamental right to privacy and an attack to our inherent right to security and safety.
That’s correct, but your point is not clear. Public infrastructure is not a closed system. If your “closed systems” have to communicate, they either build and support their own parallel infrastructure or don’t, or communicate without encryption over public infrastructure. Which is not acceptable.
