I think it depends on maintainer of the device. For me personally, LineageOS has broken a basic workflow like having Signal voice/video call. None of the IM apps are able to pick audio from microphone on my device (and various other models as well) due to a bug in LineageOS for almost 6 months. I regret installing it.

Signal. Though SimpleX is growing as a superior private messenger.

I think, OP is pointing to the fact that ECH makes it harder to block connections to mothership from proprietary apps, TVs etc. These apps could now use ECH, DoH to hide it's traffic from being observed.

But OP could always buy a better router that can proxy layer 7 traffic and block the traffic if desired.

Tailscale already has Mullvad integration. Why don't you utilize that?

Desktop = Fedora

Home server = AlmaLinux

Mobile = GrapheneOS

Router = OpenWrt

This is incorrect. It strengthens both privacy and security in a lot of ways for an average user.

Your English is perfect. There is no indication of low intelligence from the way you described your issues. B and C grade are pretty average and indicates you can learn with hard work. I think what you might be experiencing is anxiety and that is causing you to think you don't have skills or intelligence. I am not from US so I don't know what kind of help might be available for you there, but I would suggest you to look for a job with something you like to do even though the pay might not be great and then eventually your interest will take you further in your career.

FSF does not get in the way of security. FSF believes source code should be publicly available in order to even assume the software is secure or private. In a perfect world that would be nice. But in the real world, proprietary blobs are required to make the hardware functional. As long as OEMs are removed about open sourcing the firmwares, both GrapheneOS and GNU are right in their own way.

GrapheneOS is the easy to install OS among any mobile platform. Everything is through a web UI, so you are very unlikely to brick your phone. You don't need to type a single command. Also even if you brick a Pixel phone, it's very easy to install stock Android build through Google with a similar installation process.

Yep. It was developed to improve parallelization and security of Firefox. Many core parts of Firefox have been replaced with Rust implementations.

I do the same as well. Shelter is an amazing project.
