> If you're saying the PGP use you imagine would be more secure than the Signal use that actually exists... To present an iron-man argument instead of a straw-man, imagine they were comparing Delta Chat to Signal, and pointing out that Delta Chat does encrypt subject headers[0], and that Signal users typically don't use temporary phone numbers (which are harder to obtain than temporary email addresses). If you want, you could try comparing Signal's proprietary network versus the global SMTP network in terms of how secure they are against traffic timing analysis.
