That adds an even bigger layer of complexity for people to understand. The whole point of E2E was so that only the two ends could decrypt the data being transferred. If we now add "except if government agency requests it" then we're hijacking the term and making it no more meaningful that saying "yeah our app has encryption".

I'm not trying to hijack the term. Once LEO puts in the request the system stops being E2E - that's true. It would be good if this wasn't possible, but for that we need the whole stack of: open protocol, opensource implementation, signed verified release, and people keen to verify fingerprints. And if we're pedantic, also a verifiable execution environment.
