I see a bug filing, done merely by looking for certain words, perhaps with find and grep on an exploded tree. This is probably not helpful
The issue is NOT if a word form or file name containing the word fragments 'hat' and 'red' is present. Rather it is if a formal TRADEMARK (as opposed to mere identification) of ANY other party, or non-free (i.e., copyrighted and not under a GPL [former approach] or CC [present approach] or other freely redistributable license) images are present
The mere 'use' of the word fragments when used as identifiers is not a problem -- if that file is under the GPL, etc, it is free for reuse without change; if it IS changed, or a derivative work produced from teh sources that generate that file, we need to be sensitive to maintaining the COPYING and copyright trail, so a 'light touch' and thoughtful changes, rather than simply running a 'sed' bulldozer through a srouce tree is in order
Turning to the upstream sources, Red Hat initially isolated this type of content to two packages: redhat-artwork and the install time 'images' file for anaconda
In recent upstream product, I also see; redhat-logos
Over time, Fedora has acted to track down and get licenses cleaned up and reviewed, and we benefit from that effort
We at CentOS may WANT to alter a given piece of branding art, but please do not conflate what we must do with what is merely a potential 'want'
