The expanded term "K Desktop Environment" has become ambiguous and obsolete, probably even misleading. Settling on "KDE" as a self-contained term makes it clear that we have made the shift from a limited set of software components to a community providing an ecosystem of free software applications and platforms for the end user on the desktop, mobile devices, and more.
The term "K Desktop Environment" can be accurately and completely replaced by "KDE Community", "KDE Platform", "KDE Applications" or specific KDE application names, depending on what is actually meant.
For the desktop itself we will have the clearer name "KDE Workspace". The huge set of KDE applications can be put under the KDE umbrella brand using more specific brands for individual applications or application suites. The confusion about what a desktop environment is and implies can be avoided by using clearer terms in this manner.
