In my opinion, that kind of philosophy belongs only in a place like micro$oft.
Wrong, nearly every software project makes assumptions for the user. This is not Microsoft only, look at Gnome (which is much worse in that aspect than KDE).
That being said, I don't plan on moving away from kde, I just wish I could have a little more control.
KDE generally
offers you far more control than our neighbors (bluntly GNOME or Windows), by giving the user the choice to move, copy or link (in your example).
If you wish to define every tiny little bit of the desktop fine, but 98% of the users don't care about these options. It's not likely the original developers will work on that, unless someone of the remaining 2% supplies a patch.
