Is no one aware of Fedora Media Writer? It’s FOSS and the most trustworthy ISO burning software in existence. It’s only issue is that its named as if it is written only for producing Fedora bootable media. It works for everything.

GrapheneOS is both secure and private. It also supports hardware based attestation (No need for SafetyNet). It’s just that mediocre people who develop these apps do not wish to support freedom respecting platforms.

Your dumb phone is much insecure than a smartphone which has GrapheneOS or LineageOS. Your dumb phone certainly lacks secure 4G or 5G communication, cannot use e2e encrypted messaging platforms and cannot update firmware in case of security bugs.

Don’t bother videos against GrapheneOS. The lead of GrapheneOS has autism and he lacks social skills. This creates endless loop of hate talk between some YouTubers and GrapheneOS.

As a technical project, GOS is far superior and it is the most secure OS on the planet right now. The lead of the GOS has developed hardened malloc and various other security solutions that is now baked into GrapheneOS. So I would ask people to enjoy the project rather than stimulating more fuss against the project.

I agree SimpleX is superior protocol. I use it to share text between my devices. But I’m little bit hesitant to recommend it to friends and family because it is VC funded. Until SimpleX becomes non-profit or alternative implementation of SimpleX protocol starts showing up, I won’t use it as my main IM.
