f.lux is proprietary, mYself provided instructions to install it, I removed
those.
The frontend applet might be free but f.lux isn't. The package mYself's
instructions suggested to install (e.g.
https://launchpad.net/~kilian/+archive/f.lux/+files/fluxgui_1.1.8.tar.gz)
contain a non-free binary. Check Debian/copyright. Yes it's not very well
made and clear. If you're not convinced, go to f.lux's home page and try to
find a license or source. You won't.
If anybody wants to partake in this useless navel gazing, feel welcome to do
so, it's all visible here https://trisquel.info/en/node/10216/revisions
Since mYself replaced f.lux with redshift per my original advice, I consider
this case closed.
And mYself, stop being such a cry baby.
