it can. I'm not saying it does, but it absolutely can
WhatsApp? It can by piggybacking the content on the client itself. It can't read on the server if it's as advertised as following the Signal Protocol.
But that kind of functionality either need targeted deployment, or have that built-in to the client in public channel. It doesn't matter if they does it or if they can do it, the logic of that functionality still have to exist somewhere. I would believe some nerds would pickup some indicators and had that reversed engineered long ago.
Without a solid proof, I would on the err side and refrain from claiming such.
They both are bad in privacy in one way or the other. WhatsApp is collecting vast trove of data about you, though it can't read the chat itself. Telegram doesn't have end-to-end encryption enabled by default, means anyone have access to the server can read your chat history, though you're last subject to data collection.
If you're doing illicit activity though, WhatsApp is better than Telegram because the chat contents are the evidence those law enforcements are going after, not the connection. They can't arrest you because you make friends with a criminal, but they absolutely can because you have a criminal action recorded in chat history.
Say I lived there. BBC needs fundings I get it, but what the BBC contributes to when I watch VoD? Not even watching live programmes as zero of the content have BBC ever contributed. When the content is licensed via BBC, I already paid part with my subscription. Thst's a disgusting double dipping. If no one watches your programmes that's your problem, and citizens have no responsibility to keep a corporate from collapsing. This shit reminds me of how NHK works in Japan.
If I understand correctly, you want a two component setup. A PWA client for you to read the mail, and a server acts as IMAP client, fetches mails from all you mailboxes. The server will expose an API for tge PWA to access mail content. When new mail arrives, the server push a beacon via the Push API. The PWA would fetch the sender and title, and display a notification. If you clicks it, only then the PWA will fetch the body.
After a quick glance of the demo, I think SnappyMail fit the bill? It seems can be installed as PWA, and my browser does ask me if I want to give it push notification permission. However, I'm not too sure if the fetch logic happens as I laid out.
While I'm using Proton rn, I'm planning to migrate to Posteo with Addy.io for aliases. However they all cost money. If you mean free email that's not tie to a billionaire, I can't think one off my head. You can achieve "free" by hosting your own email server as it sounds you're intended for receiving only, but the electricity still cost some, plus you are doning free labor to make sure it is happy.
Despite the bad title, the article itself is worth a read, though the topics covered are being discussed long ago, but serves as a good reminder.
A point the author raises is about data security in end-to-end encrypted communications when using with AI. Remember that end-to-end encryption is specifically protecting data in transit? It doesn't do anything after the data is delivered to the end device. Even before the age of "AI", the other end can do whatever he wants on that piece of data. He can shared the communication with another person next to him which the sender might or might not know of, upload it to social media, or hand it to the law enforcement. And the "AI" the tech industry going forward is just an other participant of the communication built right into the device. It can do exactly the same as any recipients wants to. It can attempt to try to (badly) summarize the communication for you, submit that communication to any third party, or even report you for CSAM as it determines your engaging in "grooming behavior."
And the author also asked the question, "Who does your AI agent actually work for?" However, this question is already been answered by Windows Recall, the prime example of an AI agent. It collects data in an attempt to "help" us recall things in the past, but it will answer questions from anyone have access to it. Be it, you, your family/friend, or even law enforcement. The answer is anyone.
Not as "disposal" and you need to pay for it, but it would be totally fit your use case in that you want to hide your identity to your VP, reply to those mail, and in some level protect your personal information as they won't store or leak your mail, granted you don't use Gmail as a recipient address.
Use separate profile for different devices. Make a group when you chat with others.
