There's so many organisations moving away from it though. Email password recovery yes. But really, what does Proton's E2EE add to this? The email is still sent unencrypted across the internet. And only gets encrypted when it gets to their mailbox. It's not as if someone could easily break into gmail either. Unless they know your password but then Proton is just as vulnerable.
I just consider their "Security" window dressing to be honest. It totally ignores the gaping wide problem and fixes only a tiny pretty irrelevant part of it.
