> we find reasonable to have not e2e emails, not e2e file sharing, not e2e phone calls
That's where we disagree: I don't find those to be reasonable but I have to make do with them because that's where the current status is. That doesn't refrain me from using e2ee file sharing by default, or doing e2ee phone calls by default, only resorting to the not encrypted when I can't do otherwise.
I'm not saying that e2ee must be the target for everyone and is the solution to all problems. I'm saying that there are very few situations where e2ee blocks features, so for most use cases if it works transparently for the user, why not use it ? It's the next step after point-to-point encryption like TLS: if you can have it on at all times without inconveniences, why not use it ? Both of those make the overall situation better with no discernable downsides.
To me they have downsides, like being unable access your messages if you lose your device. I care about not losing my 6+ years of old messages even more than I care not to lose my 10+ years of emails.
Security is good, but sometimes truted third parties are "gooder", maybe we disagree on the next example but I like that the police is able to forcefully block some financial transactions, or that my bank can disable my credit card remotely.
e2ee encryption with convenience is also very likely to be broken by design,
