Stories and reasoning we put to our work is often not that visible. Here is my Link project, which is partly AI implemented communication system to test various transport and security measures. It's built with buildroot and all other details can be found here: https://codeberg.org/resiliencetheatre/rpi-extree/src/branch/main/link.md

You need communication resilience and security. Security cannot be black box, platform and operating system needs to be in house. Crypto agility and geostationary routing. I think you need something way better.

Signal / Apple / Notifications - All that discussion about secret messages being recovered from notification logs.

That’s obvious. How many times it has to be told to people that modern platforms are NOT designed for privacy or security. It’s not that hard to understand that. If you need those things, you should use platform which is designed from ground up correctly, every part. Hardware, operating system and minimal application on that, with proper internal context separation and encryption and extremely limited data retention.

I’ve posted about this over and over again, and people never learn. With basically every modern device, every layer of the stack is bad!
