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,
