The packager always should "explicitly require" what are the dependencies in a Nix package... it's not like it's a choice, if there are missing dependencies then that'd be a bug.
If the package is not declaring its dependencies properly then it might not run properly in NixOS, since there are no "system libraries" in that OS other than the ones that were installed from Nix packages.
And one of its advantages over AppImages is that instead of bundling everything together causing redundancies and inefficient use of resources, you actually have shared libraries with Nix (not the system ones, but Nix dependencies). If you have multiple AppImages that bundle the same libraries you can end up having the exact same version of the library installed multiple times (or loaded in memory, when running). Appimages do not scale, you would be wasting a lot of resources if you were to make heavy use of them, whereas with Nix you can run an entire OS built with Nix packages.
The first thing @seSvxR3ull7LHaEZFIjM said was: "Assange is a bit of a scumbag" ...
The closest thing to "righteousness" said was: "his efforts for freedom of information should not land him in US torture prisons like many others."
Which, being true, it's absolutely not challenged or contradicted by anything you said in response.
Note that "freedom of information" is totally compatible with "picking and choosing" the manner in which you exercise that freedom. In fact, I'd argue that the freedom of "picking and choosing" what's published without external pressure is fundamentally what the freedom of press is about.
Assagne (like any other journalist) should have the freedom of "picking and choosing" what facts he wants to expose, as long as they are not fabrications. If they are shown to be intentionally fabricated then that's when things would be different... but if he's just informing, a mouthpiece, even if the information is filtered based on an editorial, then that's just journalism. That's a freedom that should be protected, instead of attacking him because he's publishing (or not publishing) this or that.
