Many Wallpapers do not follow the guidelines set for logo usage. I know, people just do whatever, hack DRM, Torrent, and use unlicensed images, it's just a part of the internet, we are all somewhat used to it. There are many weird quirks in the copyright usage of all Logos, it's just that most people don't bother to find out or care to follow them. It took me a week to get written permission or sponsorship for every logo, why?
I did that because these Wallpapers are designed for Professional Programmers and Content Creatives. If you want show your work in which the desktop is in the screenshot online, in a Engineer forum, in a Zoom call with business, at a Convention with other professionals, at an interview, then these wallpapers are in scope with no liability attached. Even if other people do not know everything was precisely and correctly done, the programmer will and that helps provides the feeling of professionalism which leads to better work.
Secondly, the visual impact of a wallpaper is very important. Like listening to Classical music while you program the wallpaper can either be an aid or a distraction. My wallpapers all feature many precise, angular structures to aid the Professional Programming in thinking precisely. There is only one focus element to lessen distraction and it is centered so as to require less cognitive cycles to interpret. The color palettes, except for OpenBSD, are muted, and typically in gray, to also lessen visual distraction, yet provide subtle contrast as a background under semi-transparent terminals and windows.
I embedded my logo into many of them, super small, much like a oil painter would sign his art. Especially if you're proud of your work! I made the copyright 80% opaque and the logo is usually only 25px and out of sight!
