It`s not that it`s useless.

It`s that in the *real world*, getting the immensely-complicated policy 
machinery correct is next-to-impossible.  And by correct, I mean
   ``provides security, and never causes unwanted failures of 
applications``.

SELinux is extremely ornate, and even after all these years, you end up 
running up against not-quite-right policy databases that cause you grief.
   Once you`ve done a few of those, the temptation is to turn it off.  A 
properly-configured Linux server, even without SELinux, but with other
   security features like firewalling turned on, is likely secure-enough 
in many environments.
