What are you talking about? It is illegal to tap people's phone lines or to interfere with mail. Are you saying people don't have a reasonable expectation of privacy even when it's illegal to be spied on?

'Illegal' doesn't really mean anything in this, or any other, day and age when you are talking about the very rich, the very powerful, or the state.

The good thing about e2ee is that it probably makes the list of those with the ability to decrypt things encrypted e2e somewhat smaller. Fact is hacking can get to those keys. (i.e. state actor zero-click exploits your phone they are going to be able to get your private key and the messages in memory)
