For disappearing messages to work, your conversation partner has to promise they won’t take photos of their screen, and they have to promise to use an app that actually implements the feature instead of just pretending to, and the app developers have to promise to have implemented the code to delete a message when the service says it should

Is there actually a cryptographically-sound and physically-complete method for ensuring that a message is only legible for a temporary duration once it leaves your own device and is delivered to someone elses?

Hmmm, is CloudFlare known for being a bad actor in terms of privacy?

Setting that aside, no matter what you pick, you’ll be exposing your IP address, from which your ISP and/or general location may be derived

If you don’t trust CloudFlare with that information then you basically cannot trust anyone else, so maybe you’d need to run your own service and ping that instead now that you’re in a situation where you can only trust yourself 🤷

The other issue that comes to mind is that you’re only testing reachability to one address, which means you could get a false negative where that address stops working but the rest of the internet is actually fine

Without being specific, I’d try to get something with firmware updates available on LVFS: https://fwupd.org/

And you might want to check for distribution specific notes on that model e.g.

If Wayland is more important to you than AI/ML/LLMs then you probably don’t want anything with an nVidia GPU

We need a verified check-mark for true wayland users :P

Proton emails are stored in an encrypted form that goes beyond the simple authentication that is part of the POP/IMAP specifications

Proton does have open-source bridges/proxies, so they aren’t hiding these details from us

Perhaps Thunderbird could be enhanced to support the Proton features directly?

EFF still recommend Signal (and others) for people fitting various risk profiles: https://ssd.eff.org/

Google is also going with a combined approach: https://security.googleblog.com/2023/08/toward-quantum-resilient-security-keys.html
