Proton Mail CEO calls new address verification feature a blockchain

If users wan write their own key to the blockchain, then you didn't advance a bit, the verification problem is just deported to their blockchain public key (even if it is the same, you only know that, still not that the key belongs to the actual person it pretends to).
If it's Proton who writes the keys and acts as a source of trust, then it is a centralized situation and there is no need for a blockchain, a classic key server can do.
The immutable aspect of a blockchain could be sort-of interesting here (although security keys need to be changed every so often), but because of what I already said that essentially amounts to a classic case of TOFU (trust on first use) security, that doesn't need a blockchain either.
I was sending an email to an attorney. Upon reviewing the email in the send emails folder, a previous draft of the email was send, not the newest one - this can incur significant financial risk on me.
This is something Proton perfectly well knows their app does (without any mitigations). A message from their customer support:
Kindly note that we are aware that the Android app does have this issue. It occurs because the draft message was sent before it could be properly saved. If you wait for a few seconds for the draft to be properly saved, the full message will be sent. We sincerely apologize for the inconvenience this has caused.
(And wow it is taking it light, to call it an "inconvenience" when the product you are taking money from incurs financial damage in your customers)The new beta app was announced in 2021. We write 2023 and the app can still not do something as fundamental as sending an email.
Despite the cry-me-a-river communication (as in the tech debt section of this email: https://proton.me/blog/engineering-team-2021-update) from proton, nothing is happening, and I recommend everybody to stay away from Proton and all its services.
I have been on several projects with tech debt over the past years. But never did we leave the customers hanging over several years, kept charging them, and also damaged them and their reputation.
(And very mature of the official proton account to down-vote criticism)
It is really bad for an email provider not to be able to provide a reliable "send email" functionality – something you openly admit and are almost proud of not supporting.
Our team's top priority is your experience with our services, and we take your feedback very seriously, as it helps us improve daily.
We hope to see you back someday and bury the hatches. If there's anything we can do to change your mind, please don't hesitate to email us directly at community@proton.me
The tech debt you've mentioned is sadly real and we have been working on it continuously since then. We appreciate your support and understanding thus far.
