After some comparision:
1. The message is spawned by the [noscript]tag on the page.
2. On the other hand everything that looks like a script works regardless of the message. Popup menus, the player (well first time it wants the source of the videos as separate scripts)
searchbox . I can't find something that doesn't work in comparison with having noscript disabled in the Addons. (Although I can't get the login applet to work even WITH noscript disabled.....(edit: found it, the one that doesn't work is with a card-reader which I obviously don't have ^^)
3. When I run it with Noscript enabled but page allowed inspecting with F12 shows some weird token based BS that is commented out that isn't even there when running it with no script disabled.
Sidenote : Thanks for whoever wrote that sourcecode. All in one line with no indentation. easy to parse......
So basically conclusion:
Noscript does what it is supposed to, it allows the script and the site works.
But for some reason the site thinks JS is deactivated, although it most definitely isn't.
If you disallow the page it doesn't even load.

in regards to edit 2:

And the one you linked was particularly flawed, which is why it was taken down.
