No large service will survive providing E2EE. In the near future, there is bound to be some widely publicized incident where E2EE plays a pivotal role in a big atrocity or financial calamity. Then the public will demand that government, for whom it is already a worry, do something about it.
It just seems like a pipedream to me that unfettered E2EE will last in big tech.
