Gzus, quite dark comment/thought

Some answers to your first question you can find here: https://madaidans-insecurities.github.io/guides/linux-hardening.html
For the second question about in what ways Secureblue do mitigate that you can find more here: https://secureblue.dev/features
The last question about usability, is very usable. If you use Bazzite you may have a similar experience. It is not like QubesOS that isolate all processes making it even not able to use a GPU.
Not exactly a product from ublue but something in the same line:
Secureblue because of the reasons aforementioned for the ublue images where things are really darn rock solid out of the box AND because Linux is fundamentally behind in security and this project is trying to mitigate some of the big flaws.
It looks that part of it is proprietary https://docs.sailfishos.org/Services/Development/Sailfish_OS_Source/
Yeah, I get it. Disconnecting the TV is a must, and luckily I never even connected mine for many years. The thing is that I'm not sure that we can trust in the licensed devices either. Chromecast, Fire TV, Nvidia, etc... All of them have trackers as well. A PC or a Pi would have the limitation of streaming at maximum 1080p resolution for some streamers providers such as Netflix. It is quite a challenge!
Honest question how do we stream from Netflix, HBO Max, Apple TV, etc without connecting to the internet? Also, most of those stream require a recognized device to stream over 1080p. So basically, if you get a new TV wouldn't you be operating it as a old TV on those terms? The alternative that I see is keeping all that you want to watch at 4k in Jellyfin or Emby (don't use Plex it is just pushing ads) but you will need to maintain a library.
Any thoughts about Madagascar or New Caledonia?

I'm following your path leap on Secureblue, because I found the project philosophy appealing to my interest.
I don't feel the same about the others Atomic distros. I'm probably missing something but other Atomic projects don't seem to be adding much value if you know your thing for workstation home users.
Also, to the OP, reading the comments it seems clear to me that even with the best product you won't be able to please everyone. Although it definitely plants the interest on some that are coming across the topic for the first time, which I think is good. Learning something new should be on everyone's list.
