I see where you're coming from, and it's a bit of an old school view of E2EE. Wikipedia even has a section for the meaning of the term with a lot of citations requested, suggesting not everyone views the meaning of E2EE the same. https://en.wikipedia.org/wiki/End-to-end_encryption#Etymolog...

I wonder how far you would take the separation of functions. If Signal started offering a service to scan your messages and attachments for spam/malware, sending them plaintext from the app to their server to do so, does that break their E2EE? If they recommended the feature, implied that not enabling it was reckless, and didn't explicitly explain the result being Signal servers reading your messages?
