Because this is the historical (broken) behaviour of `ls -l'.  Use
`ls -lL' to follow symlinks.

They can't in general in FreeBSD-2.0.  Symlinks have the same
attributes as their parent directory.

The symlink gets resolved for most operations.  For unlink(), the
immutability of the parent directory applies (just as it does to
stop unlinking of files in the directory).
