It is so very appropriate "to commemorate that majesty in a model" and at this time especially. There will never again be new photographs taken of the World Trade Center towers. Thanks to Yoshi (and other modelers), we may see new 3D imagery of those buildings at least. You want "inappropriate" free stuff items removed? Then remove all the many model representations of torture devices and weaponry. And while doing so, remember that those things, too, are 3D constructs and do not even occupy any physical reality.
