It needs to be included in the documentation, and in a fit of paranoia I started thinking about its copyright status
Usually Commons documentation is useful but https://commons.wikimedia.org/wiki/Commons:Screenshots is confusing and not really clear for me.
Why license of software really matters? if it shows just a black triangle then it does not really matter what was license of code used to generate it?
Is Mac/Windows/Linux styling of window borders eligible for copyright? What about layout or icon in a title bar?
For specific example - what is the license of following file which is a screenshoot of a Firefix console:
Reddit is irrelevant, copyright law has plenty of stupid things but random tracking cookie values are not copyrighted as far as I know.
But what about icons, layout and so on? What is the license of that?
For bonus point: is this posting violating some license due to containing above image (probably no, fair use likely applies)
Maybe I should just declare "no copyright, if copyright applies then it is fair use and anyway anyone suing me over this can do 118818283 things more dangerous for me". Though I planned to do a full copyright review of all graphical assets in a repository and my dumb script found also this one.
