There isn’t really an argument, only a question. As in, a basic tenet of cryptography is that we can communicate over unsafe channels, so long as we trust the cipher, the final recipient and our own hardware. Maybe I don’t trust the 5G but I do trust the cipher and my computer, is that ok then? As for metadata, is there no cryptographic schemes that make metadata extraction impossible? I’m thinking like with Covid tracking apps, you can find out whether you were in contact with someone infected, without sharing any identifiable info.
