You're not wrong, but there's still a fairly strong convention that 
/usr/{bin,lib*,share,include} are only populated by (in some sense) 
non-essential components of the OS only, with varying definitions of 
"the OS". On Linux, this tends to mean "everything managed by the 
package manager", while on *BSD, it tends to exclude extra packages and 
ports collection.

Whether we agree on the terminology here or not, of course we can agree 
that you have to be bloody careful if you *do* decide to put things in 
/usr/bin yourself :-)
