@DarkMahesvara my point has literally nothing to do with existing branding. It's about using words that have meaning to people.
"Map quest"
"Office"
"Door dash"
none of these words are branded. Branded words are just a subset of that because people would know what "steam" means, therefore they can derive meaning from the concatenation "steam" "os" = "something to do with gaming" "operating system"
