I have astigmatism too and for me it looks just as bad when inverted, a blurry mess of black on white.
To me, what makes one a better choice vs the other has more to do with my environmental lighting.
- If I'm on a place with a lot of light, the screen being black makes it have reflections so I prefer black on white in those cases.
- If I'm in a dark place, the bright screen makes the screen itself the primary source of light which is not good for my eyesight, it can make my eyes feel like burning/tired after a while.
This is true, but then why not base it off Guix (the GNU distro)? ..I'm sure Fedora is full of binary blobs and not-so-free software.
If they needed it, they could still add extra software and blobs to Guix, sourced by the EU... and I think doing that would allow it to carve itself a niche (a version of Guix with more compatibility would be interesting for many) rather than sticking a white label on Fedora and call it something else. I don't see a lot of value on this over just using Fedora directly, I'm not sure if it's true that Fedora & Red Hat do not benefit from this... wouldn't their support agents be able to just start providing support also to EU OS customers if they (both customers and support agents) want? Wouldn't it make it more interesting for private companies working closely with the government to choose Red Hat as a partner when it comes to enterprise Linux?
I guess we'll have to see how much they customize it, but in my experience with previous attempts, I'm expecting just a re-skin, just Fedora with different theme. At most, with some extra software preinstalled. I don't think that's a threat to Fedora or Red Hat, but rather an opportunity for expansion.
